1992 Audi 80 Piston Ring replacement

Are S5's notorious for not being serviced?
I don't presume to know what you're looking for Alex, but buying an S5 will likely have a decent specification on even a base model, minus things such as sound package or panoramic sunroof. Incidentally, LED matrix isn't gimmicky lighting. Far from it, this will have been a very expensive extra from new, over and above standard LED lights with features such as full beam assist, cornering lighting, etc. This type of specification helps sell it down the line unless you're planning for this car to be a long term keeper. You asked if S5s are typical for lack of servicing. No, not necessarily, but its a 2017 plate, so a 9 year old performance car, so it pays to do your research. The original owner may have sold it, and it could have traded hands a few times or been run ragged on a track or indeed modified. Without some sort of service log, then you've absolutely no idea what the history is. In terms of history, especially on an older vehicle such as this, then if its been maintained meticulously, even by the main dealer on a database, they can give you a print out. If the previous owner(s) were old school, then a physical service record is better. Doesn't need to be garage stamps, but receipts in a folder from a VAT registered garage, or simply parts purchased, and service mileage, in some sort of chronological order. That speaks volumes. I've had quattros for years, so I understand tyre wear. Normally you replace tyres in pairs on the same axle. There's no dark science to it. A car failing on tyres tells you the owner isn't aware of condition, wear pattern or tread depth.4 points

Help darnest thing new engine falters and doesn't have power
Good morning Josh, Let me start by pointing out that you are in grave danger of discouraging others to help and advise you due to the unfortunate attitude you display in your last paragraph. Only you know the absolute facts about the circumstances you find yourself in, and other’s interpretation will be based solely on your ability to clearly convey those facts in a written form. The use of capitals (and particular bold capital) in the context you use them - on this forum and most others are taken as a demonstration of frustration against those who are trying to be constructive, and that is both rude and unacceptable. You emphasise NEW ENGINE (your caps), and Power Engines, but don’t quantify what you mean by ‘new engine’. Could this be totally ‘new’ à la ex VAG, stripped and fully reconditioned and fully bench tested, or simply removed from a scrapped vehicle, given a power wash down, wrapped in clingfilm and sold as ‘new’ I.e. new to you. I think it would be worth you walking back to the first bus stop Josh, and giving yourself a chance to reconsider what you write. Thanks and kind regards, Gareth.3 points

Flute whistle from after replacing PCV valve
Hi might well be with doing if the pressure slows down it may well be the valve, how many miles has the car done as around that year they are famous for burning oil where they used skinny oil control rings, problem is they let oil up but also down which pressurises the sump, fingers crossed its the aftermarket valve.

A% front suspension groan
3 pointsYou’re running a 3.0TDI V6 up front, so you’re dealing with a heavy engine. It’s not just age, it’s how the car is driven and the reality of British roads. We’re not suggesting to completely refresh the suspension, but unfortunately this is the reality with multi link suspension. If you were renewing lower front arms, do both, front and rear arms. As suggested, these are usually hydrabushes, difficult to tell if they’ve failed unless you see a leak, or get in with a pry bar. I’ve read snake oil remedies about silicone sprays on bushes to remove squeaks. That will be short lived and probably age the bush given it’s petroleum based. The only grease you can use with rubber is red grease. Similar to brake rebuilds. You could try on some of the ARB bushes as it’s a relatively cheap fix, but does mean a little bit of work if your spanner handy.3 points

Leaking water washer reservoir .
3 pointsNo idea on warranty, but I’d like to think so. If you’re spanner handy, these jobs are not difficult. Water reservoir normally accessed by removing road wheel, then inner wheel arch liner. Normally a series of Torx screws and a couple of 10mm hex nylon nuts. If the reservoir has a crack, replace. Pump usually attaches with 12v supply, with rubber pipes. It could be leaking at a pipe attachment. Main Audi dealer is £200 an hour, not including parts. This is bread and butter work for an independent garage you trust.3 points

Insurance
3 pointsWe don’t know your driving history to date, but £400 a month on insurance is insane, considering cost of fuel and running costs as it is. Unfortunately males under 25 are deemed high risk, and of course the area where car is left overnight and your job will also have impact. Use some of the insurance comparison sites, on a standard 1 litre car for example and see what comes back price wise. You can also add telemetric box, which means you need to drive within speed limit at all times and even when you drive. Additional advanced driving qualification may help, but ultimately you need to be over 25 with no claims to start bringing it down.3 points

Insurance
3 pointsHello Dillon, So that is £4,800/pa, add to that, the car’s depreciation over that year, and you really are into bonkers territory! I am ignoring any finance you may be paying, together with the annual road tax, and obviously the actual running costs of the car. Sorry to put it bluntly, but you are in extreme danger of running yourself into an economic disaster - unless your earnings are exceptionally high,or you are ‘of some means’. As Cliff says - assuming you have checked all comparison sites - you will need to seriously research vehicles with low insurance groupings, and cut your cloth to suit those vehicles. Really sorry to say it as I see it, but it’s madness to have to spend a significant amount of amount of your working time to ‘feed your current situation’. Regards, Gareth.3 points

start/stop
3 pointsThe ability of a battery to crank and fire the engine is not evidence that it is in good shape. That was true years ago in the days of points in distributors, but not since the advent of sensitive electronics. I suggest you get the battery properly tested (not by a multimeter). I'd go further and say that if it is more than five years old you should renew it irrespective of the test results. Don't forget to get the new battery coded to the car.3 points

Reacting to help and advice given.
3 pointsApologies for the gripe, but the forum has recently suffered from a spate of what can be termed ‘Post and Run’ new members, who seem to think it’s perfectly acceptable to post a plea for help, and simply not return to view the help given. In a more diluted form, help is offered, but is very rarely acknowledged even via. a simple press of the Like button, leave alone a posted Thank You. The last part of the gripe is that we frequently have to ask for additional information, and this extra detail often never materialises. Please remember, everyone who posts replies do so without payment, but it certainly does cost them in time - in terms of the Moderators and Admin back up - a lot of time. So a special plea to all on here who post needing help:- please be respectful enough to acknowledge any help given, rather than simply accept it as a no-cost, no time of yours, free advice service. It’s wearing thin folks, so if you want to retain this service, please respect and acknowledge its benefits. Thank you all for reading this, and above all, agreeing to adhere to the respect that is needed to be shown. Kind regards, On behalf of the Moderators. Please note:- This request is to all members, not just new ones. p.s. Please avoid using non specific locations such as U.K., England etc. etc.3 points

Help darnest thing new engine falters and doesn't have power
It's true I can not help you Josh if you are not prepared to either do any testing or provide suitable information to aid a possible diagnosis. If all you want is speculation and guesses then you don't need my help. After all you claim to be "fairly car literate and I'm usually able diagnose and know the problem..." I looked up Power Engines and saw the company supply new and re-conditioned engines, so can you be sure the engine you received was genuinely new? The company lists this for your car: https://powerengines.com/collections/all?filter.p.m.custom.make=Audi&filter.p.m.custom.model=Q5&filter.p.m.custom.year_multi_selects=2016 The price of $3199 is impossibly low for a brand new engine, even before it is shipped from Germany, so what do you conclude from that?2 points

A1 A/C blocked
2 pointsHi I would get someone else to check if the system has any gas in it, most independent garages have a decent aircon machine and will check it by seeing if it has ay gas and then pressure checking the system for leaks chances are its either run low on gas or has a hole in the radiator either way Cliff was correct when he said they can't block, therefore I would give the ZOONS at Halfords a wide birth.

Audi New Model A5/S5 Avant Experience
My tuppence worth. Problems with the 25MY B10 are well documented and although it shouldn't happen, and in my opinion should have been addressed before the 26MY was released, to Audi's credit, they have acknowledged the software issues. It's something I would have been able to ( and still am ) reject the car. Outwith the software issues, my car came with a couple of faults - sticking brakes and an annoying rattle from door panel, both of which were rectified at dealership. That can happen to any car regardless who the manufacturer is. A smearing windscreen wiper typically means both the rubber and the glass need cleaned. First thing I've done with every VW group car I've owned is replace the wipers with Bosch aerowipers, but thus far it's never been required with this A5. (They look very similar to the Bosch ones) Software: I don't get as many system failures since the 'open/close' door solution but I'm led to believe that the software fix for MY25 is now being rolled out - EV cars this month, ICE next month. You should be notified via My Audi app when the update is available. It'll require a dealer visit. Regarding the battery. Welcome to modern cars. Our other car is a Toyota hybrid, one of the most reliable cars on sale. That too has already undergone a battery replacement due to the battery management system. The 'fix' if you can call it that, is the car now notifies me when the battery needs attention and the car has to be driven to charge the battery. Modern cars don't seem to be able to cope with sitting doing nothing for 2 weeks as they're constantly monitoring themselves. If you're knowingly going to leave the car sitting for several weeks or more then best solution would be to put it on a trickle charge. That goes for any modern car but especially for those that you're able to communicate via a mobile app. Hope that's of some use.2 points

2 pointsLeave well alone. My wife had one. Great cars, ahead if their time. They are a potential classics down the line. They made a 1.2TDI version, very rare, plus Storm editions in Papya Orange for example. Nothing to be gained from extra 25hp. It was a fast little car on account of the aluminium frame, but the brakes were pretty standard. Save your money. Sourcing parts is becoming the issue as it is.2 points

New 226 audi q3
2 pointsI know how you feel Martin. In the first few weeks I had my Q3 it seemed I was emailing Audi nearly everyday with another new MMI software issue, all minor stuff, but annoying at the time. It took the enjoyment out of owning a new car. However, over the last few weeks things seem to have settled down and I now rarely get any issues, just occasionally the radio may not come on, or the drivers display will revert back to the rev counter from my chosen screen. As a result, I am starting to really enjoy the car and look forward to driving it (but maybe not as much as riding my motorbike 😉) It was mentioned on another forum that perhaps too much is happening in the software at initial start up resulting in some functions failing. Recently, I've taken to pushing the start button to bring the MMI on whilst I fasten my seat belt, then start the car, whether this is the reason I'm having less issues, or perhaps there has been an 'Over The Air' update to fix some minor issues, I don't know. Regarding Francis' issues regarding various warnings flashing up momentarily on the MMI about system failures - I've had this happen 2 or 3 times, again, I've put it down to the software being slow to boot up, with certain systems showing as failing, then correcting when it fully boots. You get something similar if you manually reboot the MMI, various features show as failed, such as the Navigation system, but they all come back as the system completes it's reboot.2 points

A% front suspension groan
2 pointsOn multi-link suspension, start with the cheap stuff first and then progress. The lower arms are likely hydrabushes, so they leak when they fail. I changed mine at 65k on a 17 plate A4 Allroad. Lemforder is OE specification. Also check the ARB bushes on the sway bar. Next the ARB link, then finally the top arms. Top arms when they go, will knock. They are usually visible if you hold and 10-2 position and try lateral movement. The only thing left is the top mounts and the bump stops on the suspension shock. If you're changing anything, then always do both sides. Lemforder and Meyle HD, that's all I'd fit. Given the state of our roads - also look at the coil springs too. you can drop an inch and not even know about it. Not sure with A5, but on A4 Avant, the rear spring seat/bush corrodes from inside out, so although cheap from Audi, you're looking at labour to fit unless you're spanner handy. I did it myself so as not to disturb eccentric bolt. If I was doing it again, I would just mark then remove that bolt. This is complicated further if its quattro drive. Car will need alignment check afterwards.2 points

A6 2018 C8 3.0tdi quattro drivers mirror indicator
Hi, For what it's worth; I was lucky enough to have the Technology Pack on the A6 I bought, so I have the LED Matrix headlights and dynamic indicators on the front... I found some side (mirror) repeaters on eBay that were also 'dynamic' and had tinted plastic lenses so look black, like the rest of the car/mirror, until lit... And then the lights 'sweeps' outward in sequence like the indicators both front and rear. Cost me £30 for the pair, fitting is exactly as listed above, and they're still good 5 years later. Took the 'chinese knock-off gamble' and won, in this case. Hope yours are as easy as mine were to fit. Best Regards, Tigger2 points

Are S5's notorious for not being serviced?
Getting a car to operating temperature is important for a number of reasons. Efficient fuel combustion in petrol (helps reduce carbon on intake valves and sparks), oil pressure and viscosity to lubricate engine components as oil heats up, battery health as alternator recharging battery. B9 battery health comes up a lot on the forum, and cars very susceptible to electronic issues if battery on the way out. New AGM battery probably £250-300 or so and needs coded to the car. Short runs can potentially lead to water vapour as it’s not evaporating in engine and turns to sludge. Regular oil changes can help combat this. Battery drain, as alternator hasn’t fully recharged battery. Engine heat can help burn off carbon to a degree, but the car will always generate carbon. I’d recommend at least 30 mins to an hour on a motorway or A class road once a week to help. Short runs over time are going to introduce issues. As Stevey has suggested, check out VAG Technic YouTube. Few horror shows on poorly maintained engines, primarily S4, but also S5. I particularly remember this one. https://youtu.be/y-d0ymYi09o?si=0YcncBnJxZvYvh2A There’s also an issue with rockers on some of these cars with needle bearings that disintegrate, as Audi subsequently revised the part. Regular oil changes can help.2 points

A6 2018 C8 3.0tdi quattro drivers mirror indicator
Part is called turn signal indicator. Right hand side is 4G5949102B. Double check that with main dealer based on your registration. Think it should be around £45. Avoid Temu or EBay. https://www.lllparts.co.uk/catalogs/audi/RDW/A6/798/9/949/949000 To access, normally pop out glass, see if any screws, then prize mirror cap off, again using the trim tools, as usually clipped in. Unscrew the existing module, until electrics, and fit by reverse. Can be more complicated if lane assist or camera fitted. This is 2015 A6, so should be roughly the same. https://www.youtube.com/watch?v=Hqps2U43fzI2 points

What to check before I buy? (C6)
2 pointsYou want a year's MOT on any of these cars. If buying privately, do your research. You can pull previous MOT history via government check. Also speak to owner. Genuine owner will have paperwork and lots of it, plus history. For these sort of vehicles, keep your search area tight. No point travelling for 'immaculate example' only to be disappointed. Always drive a car from cold, and cross reference vehicle VIN on inspection. For a car you're prepared to buy, and given we live in a world where we're surrounded by scammers, then pay for a vehicle report such as carvertical. RAC offer something similar, but less detailed. If you have VCDS, definately scan the car. Diesels on the whole are robust. At this age, its Euro5 technology. Regular oil changes are key to engine longevity. Anything on long service intervals 15-18k intervals, walk away. All 2.0 TDI engines will be belt driven, so again, when was toothed belt done? My advice is 60k miles or every 5 years plus waterpump. If any cars have panoramics, then check carpets, and headlining for water leaks. Test all electrics, central locking, etc. Sat Nav likely out of date, but it is what it is. Scuffed wheel rims, someone can't drive. Alignment will be out and I'll bet it pulls to the kerb. Check coil spring height. Easy test with your hand on level ground from tyre to arch.2 points

I've bit the bullet
2 pointsHi the B6 is about the best compromise as they work with either conventional ride hight or factory lowered just remember to release the piston from its transport strap and push it all the way down and let it return at least six times to prime the monotube system as these work differently from twin tube, yes the rear sub frame has voids but you can get around this by using a product called Bilt Hamber, they do a range of rust removal and rust proofing, it ain't cheap but its top notch, my friend did his 1981 Porsche 911 with it a few years ago and it definitely works, with regard to the bushes poly is easier to fit but gives more road resonance when fitted and will take at least two years to calm down and bed in to an acceptable level, a very wise engineer I met that looked after racing cars at Snetterton once told me if you want good handling on a road car use standard heavy duty springs and stiffer shocks and a good branded rubber bush, if you get a new frame just change the bushes for peace of mind and bare in mind how long the originals last, use Meyle or Lemforder, if your mate is bringing power tools for the brakes tell him to not use them until you have the bolt moving which requires a blowtorch and plenty of plus gas anti seize and patience as these threads will ring out given half a chance, if you consider the amount of heat a calliper works with you can't realistically overheat them, once off I would replace the units anyway in view of the fact that 90% of callipers are refurbished even the dealer units. and bolt wise invest in a Sealy Wall Drive sockets as that system will never round the the bolts off as it grips the flat sided bit of the bolt.

Help darnest thing new engine falters and doesn't have power
Hi the idea of publishing the codes you have is to narrow down the components that may be causing this, you say that the vehicle was laid up for two years and you have blown two HPFPs therefore I would suggest that the high pressure side is in overrun which is eminently checkable on live data, my guess is that its the fuel pressure regulator playing about, this meters the fuel pressure within the rail and is electro mechanical therefore it can stick slightly and cause insufficient fuel to the rail causing flat spots or stick wide open and the HPFP tries to keep up with what it thinks is demand, the return system just loses what it won't use, using live data check the rail pressure at idle and then through the rev range and see if the figures add up, don't know what the rail pressures should be ideally on the DETA engine you have but I know if the lift pump in the tank is high around 600lpm you have a problem further up.

Help with some issues
1 pointHello everyone, Wondering if anyone can help me. A few weeks ago my EPC light came on and immediately went into limp mode and started jumping when driving at 5mph. After a few hours I came back to the car and it was fine so I drove it to my storage unit. I came back the next day and when starting it the EPC light and EML light were illuminated and the idle was quite rough. I came back to it about a week ago and all the doors were locked, the key isn't unlocking it and the barrel of the central locking isn't even turning. The ignition seemed to be on aswell. I'm really at a loss of what to do. We had some hard rain that week the vehicle was unable to be opened so im hoping water hasn't gotten into the BCM but I'm not sure.

Are S5's notorious for not being serviced?
Wouldn't go as far as to call Evans Halshaw a dealer, they are a reseller at best, and 37k miles on a 2017 car is very low. That sounds like a careful owner, however where's the information to back it up? £23k isn't small change either. Quick check of the MOT history - so either tyres or coil springs that it's failed on. Sounds odd to fail on tyres - so that's a potential red flag for me. Regardless of mileage this should have had oil changes probably every 5-8k miles. Personally I'd walk away. I'd rather higher mileage and history (doesn't need to be main dealer), but you want receipts and lots of them. People who look after their cars tend to document any work done. Why? This is a cam-chain driven car, if it's been on long service intervals, then you could get potential chain slap on start up, then it's an engine out job to replace, plus guides. Tiptronic transmission is bullet-proof, but I'd still look to do a transmission oil change on or around 8 years or 60-80k miles so that's due too. ZF-8 make a specific kit. https://www.autotrader.co.uk/car-details/202604261891333? This is a 2018 car on 54k, but full loaded, panoramic, red leather, LED matrix, and yes more expensive at £27k. Unfortunately there's no short-cuts with these cars. This one has full history. Goes without saying I'd be running an independent check with car vertical or such like, full scan with VCDS, etc.1 point

Brake servo restricted
1 pointJust to add my two cents, 2016 A4 Avant b9 190 quattro 100k miles C11EC04 with the dash bit saying brakes restricted / start stop gone etc etc. It popped up as soon as I started the car and was after the car hasn't been used much in the last two weeks and perhaps nor for 3 days before that (seems common that if they sit the sensor dies). I drove it 10 mins and then came home as I knew it could brick the ABS eventually. I work on cars alot and even this got past me.. I changed the sensor to a new one from amazon £15, upon plugging it in I had the exact same code. I fiddled with it on and off the car, I then started getting codes for brake boost pressure sensor short to GND and short to POS, sometimes one, sometimes the other, sometimes combined with C11EC04 sometimes not. For reference C054B00 is the code for GND or POS I forget which. So sometimes that code by itself and sometimes that combined with C11EC04. I thought perhaps it was my ABS unit dying as I knew the sensor was good and I also tried an exact same oem audi sensor from my A6 C7 for good measure, same code games. And my amazon sensor worked fine on the a6 c7. Long story short (haha) the sensor was not plugged in correctly. It was not quite seated enough. I removed the rubber seal (car side plug) and seated the sensor properly, this time making sure it latched fully. All cured. To add, it was actually semi latching the first time and visually it looked normal, it pushed most of the way in and it wouldn't pull off from a small tug, making me believe it was properly on. Before you mess around try using a needle and working the small white rubber water seal out, and making sure the car side clip is fully backed off then push the sensor on all the way, latch it properly (it shouldn't be able to be pulled out at all by any tugs) and then plug the sensor back into the car brake booster reservoir. I knew before I started it again that the problem was solved. It just wouldn't yank off this time like I could before, and the short to gnd and pos suddenly all made sense. Goodluck !1 point

Ai the mechanic?
1 pointIf the Audi dealer found no faults at the first diagnosis how much reliance can you place on his second attempt? Then there is AI which has given you a list of possible faults, but no certainties. Are you going to spend money on that basis? I suggest you find an independent VAG specialist who can test the car with a decent code reader such as VCDS, and let him do the diagnosis before committing to any expenditure.1 point

Avoid confrontational responses to post content that may be different to your own personal beliefs. Everyone has their own opinion on different matters and this provides for diversity, so please avoid an argument. Be polite It doesn't cost anything to have manners and would be appreciated by the community if you included 'please and thank you' as required in your posts. Keep it clean Don’t post anything obscene or sexually explicit. Respect each other Don’t harass or troll anyone, impersonate people, or expose their private information. Be respectful to Moderating Staff and other members at all times. No politics or religion Nothing starts a fight faster than politics or religion, so we don't allow those discussions. Keep personal information private All posts in the forums are easily found via search engines, so unless you're willing to expose your information to the world, please do not post telephone numbers, e-mail addresses etc in your posts. Have a little patience We are a club made up of members who have to work days or nights so can’t always reply straight away, someone will get back to you as soon as they can, so please be bear with us. Thread titles Be accurate with your topic by giving a brief sentence of the problem, hint or tip you would like to get across to other members. These are not concrete terms with precise definitions — avoid even the appearance of any of these things. If you’re unsure, ask yourself whether you'd go on TV and publicly say it on camera. This is a public forum, and search engines index these discussions. Keep the language, links, and images safe for family and friends. Follow Up Please find the time to follow up your post with a conclusion (such as; that worked, tried that but didn't work, etc) so contributing members can see whether their advice and suggestions worked in this instance. You may receive an email asking you to add a conclusion to your post, please find the time to return to your post and marked it as solved.1 point
