Hello there, I'm back again! Here's my first week of usage of my new C5 2.5 Tdi. Actually the car is still with me and not in the mechanic's shop due to some delays on other cars in his shop... but it will be soon there! In fact I made a "To Do List" for the mechanic just to track down all the flaws and problems the car actually has and has to be repaired or enhanced, such as: Timing belt + water pump + auxiliary belts Control arm kit Automatic transmission oil + filter kit (ZF 5HP19) Check and clean all radiators (including the transmission cooler. The transmission shifts and downshifts very poorly once operating temperature is reached. Possible issue with the transmission thermostat) EGR valve Swirl valves Excessive smoke under medium to heavy acceleration (EGR?) Check turbo and intercooler pressure and vacuum hoses Warm air from vents when climate control is off (possible issue with engine thermostat or cabin heater core) Injector sealing rings (cold start difficulty with accompanying bluish-white smoke) Install Bluetooth system in car radio (ask electrician friend) Brake pedal very hard, and brakes "stick" briefly after pedal is released. Possible brake fluid issue Power steering pump sometimes noisy. Check fluid level and replace if necessary Check rear suspension height Check and replace dual-filament rear brake light bulbs if needed Replace windshield washer pump Apart from that, she sits quite happily on the road again!

a part 2 to come as got to change the usb and heat shrink came today youtube video

Yeah know it's illegal but it was either that,or, a god knows how much bill replacing parts that actually where working as the garage I took it to for diagnostics could only narrow it down to either the adblue pump (£800+) or an injector (£600+) and they couldn't even say for deffo it was either one. To be fair I did speak to somebody at Audi and he said he'd never know a pump to fail and was more loto be one of the lines. But needed the car for work, so....went with the map. Car feels great though. Picks up better, smoother the all the gears. Drives like it never has since we had it. It's 10yrs old this year and feels like new. Do like Audi engines just !Removed! expensive to keep on the road.

Hello again lads After a bit of advise again if possible. Rear door mid speakers have blown BOTH sides if you can believe that (blame the missus, she does crank the sound up). Anyway can't find any info on line about them. I know the part number but not to interested in paying Audi prises. So does anybody know anything about the power output and the frequencies and the ohms. Not planning on replacing everything so I would like to just get something that will slot in with the system all ready in the car. Part number for the original is 8K0 035 411 made by some company called ASK Industries in Poland. I always thought we had th B & O system but apparently not they have a "A" suffix Thanks Simon

Could be leaky injectors. Not suggesting you replace the injectors. You could pull them, clean and replace the copper seating washers. Not sure if there’s an ‘o’ ring on the main mode of the injector too? If you do pull them, replace the bolts, they are stretch bolts and torque to yield, once only. Use a little ceramic grease on refitting. If an injector was damaged, I’d expect a further error code. Any new injector needs to be coded to the car. P0420 error likely to be inefficient catalytic convertor. Not sure any of the off the shelf products work. If it were me, you could try Forté products, including injection cleaners. Another option is to access primary oxygen sensor to inspect the cat itself. A lot of work, yes, but only way to confirm visual inspection with endoscope camera (with light) that works with your phone, just to be sure it’s not broken up. Bear in mind this was a crash damaged car.

Don’t skimp on budget is my advice. I understand you’re looking at B&O, but that needs to dovetail with car model, engine and gearbox and even colour. B&O was expensive feature, so it’s not likely to be found on poverty spec car. If you find B&O, then it’s bound to have leather, folding mirrors, possibly virtual cockpit would be my experience. Retrofitting anything is expensive, and usually you need VCDS to remove codes, even if plug and play. I know this is on an Allroad brochure (2017), but it elaborates on the comfort and sound packs. https://autocatalogarchive.com/wp-content/uploads/2017/09/Audi-A4-Allroad-2017-UK.pdf Trim level aside, you want history and lots of it. On cars that have been on long service intervals, personally I’d give them a wide berth. No oil should be in the car for 18k miles. Be prepared to travel too, once you’ve done your due diligence checks. Additional checks such as Car Vertical which you pay for are useful.

VCDS Hex2, absolutely no question. You can source from Gendan. You get OBD cable and lifetime updates. 3 VIN licence will cover your car, plus whatever you source in the future. Works across VAG range of cars. On air suspension, if you’re fitting yourself, you might even need specific feature to ‘relearn system’ after installation, similar to panoramic sunroof synchronisation or one touch windows. On VW Golf 8 for example, you can’t even swap out rear pads without access to ODIS which is dealer level software, so you can see the way things are going.

Hi. Just wondering if Audi resolved the camera issue? Mine has been in 4 times over the last 18 months and always not fault found. They had the car for four weeks once. Said they’d updated the software and it worked fine for 3 months. it’s just frustrating as you never know if it will work or not then sometimes it’s starts as the blue screen and then after 10 or 15 seconds it’s as it should be

So two weeks in and i am loving my A4. But I want to add my own touches too it. So I want to add an SLine badge to the front grill. Looking through Ebay etc there are so many to choose from. Does anyone know the correct one for the B9.5 with the Hex Grill.

Definitely worth speaking to autologics or Audi retrofits regarding android auto to give you an idea of cost. Check YouTube for buyers guides. Regarding quietness all the cars will have the same sound deadening etc. Check this thread regarding B&O https://www.audiownersclub.com/forums/topic/25250-b-o-is-it-genuine-or-just-a-rip-off/

Could it be a cam sensor or lambda sensor

I'd recommend you speak to your local Audi dealer who will be able to tell you what outstanding recalls you have.

Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂 looks lovely 👍

Good luck!

Hi, Hi have audi a3 2014 2.0tdi sline. It suffers with a starting fault. (Intermittent) car turns but sticks then after 2 or 3 turns it starts. Drives fine. I'm having error codes p223700 and p031400. The camshaft position sensor has been changed the belts etc have all been changed. Oxygen sensor has been changed. My fuel flap doesn't lock. I'm thinking I may have an electrical issue. As stated the car maybe fine for a month or two. If I adjust the heaters that work fine it's like it can make the fault happen. Any suggestions ? Thanks in advance

Ayoop folks, well my local garage with whom we have a good relationship (using them for 23 years now) have agreed that as I currently have about 6cm of ground clearance (one passerby said it looks "sick", I said it was very ill ) and even getting off the drive is nigh impossible, they'd drop by with the VCDS setup and scan to see if the fault can be identified.....I'm beginning to suspect one of the legs has given up the ghost but can't tell which one......and jacking the car is gonna be a nightmare but I'll find a way. I'll come back with an update when she's been scanned. Stay tuned folks.....

Try colin ludwell cars in Bristol Had one 2017 252bhp. Great car

Yeah, mechanic replaced power steering column with a used one (costed around ~300 euros all in), haven't seen this issue once ever since.

Bought new sensor from audi and tried to replace it myself. I was able to release the wiring clip but not able to release the clips at either side. Any advice?

Hi Gromlog I have the same isue... did you reslove problem?

Hi everyone, I'm currently a happy owner of an A4 but giving serious consideration to a petrol Q3 Sportback, not sure whether to go for front wheel or quattro drivetrain. Any tips here would be helpful thanks. More importantly, is there anything you discovered after you got your Q3 that you wish you'd known beforehand? Thanks in advance.

Thanks gents for your replies, i’m still investigating the problem, once i have the solution i will put it here although feel free to continue with any advice cheers Dave

on 2017 im getting a fault on antenna to infotainment system in passenger door it says any one got any idears some one said its a recall and can get it sorted for free is the right does any one no ???????

On mine it feels like I'm running low on fuel and the engine is stuttering. The RPMs also judder slightly. As soon as I start accelerating, even lightly, it's gone. In my experience a good way to manifest my problem is by cruising at low speeds (30-50km/h) and just barely feather the accelerator in a lower gear - e.g. 3-4th. No acceleration, just cruising at a consistent speed. I can also let go completely and very lightly press again and it might start doing it. Same happens at higher speeds, but due to the high gear, it's less noticeable. It's worth mentioning that it's not happening every time. Like I previously wrote, it's a bit hit & miss. I have the feeling that it's happening the most when the engine is still not up to temp. I hope this helps.
