No problem Parm, but if you decide 0w/20 is the way you will go, it won’t just be any 0w/20 - or necessarily a Shell brand because you can get it at a discount - but it must be confirmed to satisfy whatever VAG’s specification is within that grade.

You're best getting one of the same gearbox code ideally.

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

Thanks Gareth. I'll consider this in my decision. I'm complete novice so will take advice given from experts. 1 up on the 0-20w in which case.

Taking your belief that if oil is thicker it lubricates better -if so, why not go all the way and fill the sump with grease! Deviating from the manufacturer’s recommendations is entering a territory you should not want to be in, but it’s your car and your choice to ignore VAG’s advice and the advice offered on here so far. Good luck with whatever you choose to do, and I remain happy that the advice I’ve offered you is based on sound logic. Having said that, please let us know what you eventually decide Parm. Regards, Gareth.

In all honesty it's because 0-20w is such a low viscosity oil. Been reading up in numerous places that if the oil is thicker it lubricates the components of the engine better. Main reason for 0-20w was more to do with emissions and fuel economy which if I'm honest is less important..I'm more concerned about the long term health of the engine .

Ok Dave, many thanks.

If you can live with keeping the oil topped up you might be surprised how long it survives, and maybe get a drip tray to leave under the car when it's parked overnight or longer? An old paint roller tray or similar would do if you know where the oil is dripping from.

I'm known for them mate, just ask my wife!

Hi everyone 😀 As I just joined, I thought it best to intro myself here and showcase my pride&joy on 4 wheels 😅 I've had my car since 2023 and still have the feelings it's new to me. While I've had other VAG cars before (Golf MK6, Skods Fabia 2015, Skoda Octavia 2002), this my first Audi - wow, it's such a difference in certain aspects. I do need to get some repair work done, which I'll ask for advice in a separate thread. For more photos, check out the post I made in the members gallery. Comments and questions are most welcome.

The general concensus is my car is nearing it's end. I will continue to put oil in it for as long as survives. It's such a shame as this is the best second-hand car I have owned for 13 years - it drives well, the bodywork and other mechanicals are good but without an engine... Thanks again guys for your time and knowledge. Much appreciated. Kind regards, Colin Dimes.

Wrong thoughts Dave.

Welcome Parm and thanks for joining. So why do you want to move away from 0w/20 if ( in caps) this is the grade specified in your handbook or some other official VAG publication? As well as the grade, there will also be a VAG specification within that grade which the necessary oil must specify - as they say on the tin. Although I use the correct grade of Shell Ultra for other cars, I only use VAG’s branded oil -Quantum- in our 176K A3. In case it helps, I use their Longlife 3 ,but treat it to an annual oil change irrespective of the much lower mileage covered annually. I usually buy from reputable sellers on EBay. Kind regards, Gareth.

Thank you. I believe it was low fuel pressure, changing the fuel pressure pump (I’m so rubbish with cars as you can possibly tell) under the back seat did nothing, the guy at the garage said he thinks it now could be the ecu, they checked for any visual damage to it and nothing, I spoke to someone who deals with ecu’s and remapping and he said he doubts it is that

Where was the car parked while you were away mate? Just wondering because there have been a lot of horror stories in the press recently about airport parking companies using (and often damaging) vehicles while the owners were away.

Ah, I thought the above was the question, I was just trying to help in case you'd missed it.

Welcome Jason and sorry to read of your problem. With note to your thread title of ‘Low pressure’, what pressure have you been told is low, so members can better relate to your issue? Regards, Gareth.

Hello, desperate new member here, a couple of months back whilst driving I would notice my car 2015tt tdi ultra , hiccup , just a very slight jump, could be anytime at any speed, over a little time this issue was getting worse, could be 4-5 times in a row, I took the car to a garage who checked which codes came up, of which was fuel rail, speed sensor, camshaft, (sorry I don’t have the codes to hand), the garage wiped the codes and I drove off waiting for them to reappear. The issue at this point is now getting worse, the engine warning light came on, hillstart, ttps, esp etc. i returned to the garage and they tried a new camshaft and crankshaft sensors, these had come up on the codes, again, this didn’t sort the issue. i took the car to an Audi specialist and after much of the same they have changed a in tank fuel pressure in the tank under the rear seats, checked all the wiring in the engine for any wire issues, still the problem persists. The cat is getting gradually worse, and as said above I don’t have the specific codes but he did say it’s co stay my bringing up spied sensor and low pressure. He’s apparently done maf readings which came up normal. does anyone have any ideas please what thos could be, I’ve paid out a small fortune recently and not seeming to get anywhere. thank you

Thanks. We're scheduling the appointment today. We had the diagnostic software updated but they didn't check anything else out on that appointment.

I can't help on that score, except to say you need to find a way to test the output of the LT pulse generator (the Jetronic unit) before worrying about the coil.

Springs simply do not break when motionless, so it must be air suspension which is known to have problems with leaking bags, compressor failure and height sensor faults. If the car is undriveable it will have to picked up and taken away for repair.

Hi Cliff I believe it's KE-Jetronic system there are no points involved. I tested the coil firstly by using a lead and cranking no spark from the coil I then removed it and did an ohm test which I'm sure was within the range. Now I'm after where to go next.

Get it tested promptly in case it is related to this topic: https://www.audiownersclub.com/forums/topic/24906-alternator-failure-related-to-mild-hybrid-system/
