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.

I have never had any problems took car out dropped roof electric, all fine went diy store roof still down locked door by key later wen home went to put roof up not happening all solenoid sounds working light on panel flashing then the boot won’t open by key or fob but once again all solenoids clicking working. any help please .ps can I open storage manually. Regards .

Thanks for the tips Gareth - I'll take a look. Here are some more photos of the blower Dave, let me know if any other angles would help. Unfortunately I think the one you found wouldn't fit - if you can see it has the electrical connection in the middle of the fan, whereas on my one the socket is off to the side.

Newbie Audi owner A8L 3.0 TDI Quattro

Hey guys, new to the forum! Ive bought an insurance write off audi s3 2014. All work has been done and ive finally got it out on a drive yesterday! All runs and drives perfectly. Only issues I'm having at the moment is; Loud start up revs sits at 1k for a minute then drops and quietens down during idle (am I right that this is normal?) Engine oil level ok Rough idle, it stutters like its about to stall maybe every 30 secs? Bit smokey during idle (fault code shown for this) Also loud rattle when engines warmed up, seems to be coming from camshaft cover top end. Disconnected both camshaft magnets but didn't make a difference, (rattling wasn't loud at that point) I have plugged diag in and the fault codes shows; Ive changed spark plugs due to misfiring when I first bought it, I don't want to throw money into the car for replacing the wrong parts. Can anyone point me in the right direction on which part I need to be looking at?

Your best bet is to get a complete Bose set up from a donor. You'll need the sub too. I thought it was under the passenger seat. But you've also looked in the boot too. Should definitely be in one of those locations I think

Thank you so much for the suggestion. The oil cooler turned up (ordered from Autodoc for £38 with gasket) and was fitted a few days ago. The oil cooler gasket was also replaced and the oil filter housing gasket was wrecked and botched with silicone before. This was also replaced. Also a new brown low oil pressure sensor from febi bilstein at the same time, to replace the official Audi one, although the last one was changed recently too, thought I may aswell do that. Had a few spirited drives to try get the warning up again, but nothing so far! I'm going to mark this as a solution for now and if it somehow happens again, I will update this thread. As things stand the oil cooler and gaskets seem to have done the trick. My greatest appreciation to Cliff for this suggestion, thank you so much. I'd love to buy you a drink sir!

Hello there, I'm in the process of trying to find an Audi A4 B9 to buy and have a few trim related questions. A little background. I'd like a upgraded sound system, and quietness (to enjoy the sound system) is high on my priorities. Nice to have are leather seats and Android Auto. Budget will only really stretch to an older model: 2016-2018. I've found an SE with a B&O 3d sound system as part of a Comfort and Sound Pack 1) Are a subwoofer and a spare tyre mutually exclusive (i.e can you have both or is it an either/or scenario)? 2) if I get a basic (SE) trim, apart from the seats and suspension and styling are there any structural differences to the Sport/S-line? Especially as regards sound proofing 3) If I got some S-line seats (I've seen some on eBay) could I fit them into an SE 4) I believe I can get Android Auto on an older B9 with a retrofit kit. Does anyone have any experience? https://integratedautomotive.co.uk/product/audi-mib1-mib2-mmi-retrofit-carplay-and-android-auto-kit/ 5) What else does the Comfort And Sound Pack include apart from the sound system Thanks in advance Phil

OK David -missed that last sentence. Possible coolant temperature sensor that senses the coolant temperature and signals the ECU to provide the correct mixture in relation to coolant temperature?? They can fail to an arbitrary condition where starting and running mixture is too weak.

So are you fitting a new track rod end, and if so what brand is it and where did you buy it from?

Hi, Selling my 2013 A8 Black 4.0 TFSi, 91,000 miles. In great condition, MOT till October 2025. If any interest i have plenty of pictures. £11250 Im in TA6

Nor the 2nd for me Jake.

Hello Tom, Returning the car to the seller 5 months on??? 90 days is a typical warranty period. Your issues maybe (just maybe) associated with your statement ‘…done barely any miles on it…’. On the basis of eliminating simple low cost investigations, it would be well worth getting the battery efficiency checked - Halfords stores will do that. Spurious messages are often associated with below par battery efficiency, and your situation will be aggravated by periods of lack of use. Take the car for an approx. 30 mile run before getting Halfords to report on the battery’s efficiency. Please let us know how you get on Tom. Kind regards, Gareth. p.s. worth getting the alternator output checked at the same time.

Definitely the best option. As let's face it, the screens got to come out anyway.

Thanks for the response, know of any good businesses to send one off to? Thanks!

Hell Ashleigh, I’m sorry to hear of your on-going issue, but to be honest, I’m not at all surprised, and although my reply isn’t going to help your case, it may well serve as a deterrent to others who may think about following the same line of purchase. As I see it, the dealer should have sorted out the U.K. registration before (in caps) advertising the car for sale. In your case he has ‘got away with it’ by not completing the necessary involved work before selling you the car - without U.K. title. You are now realising that this is a rather involved process which depends on your (in caps) effort to sort out. Moral:- never buy a vehicle without a U.K. V5. I’m sure you will sort it eventually, but this responsibility should not be yours. Good luck and kind regards, Gareth.

You'll need a diagnostic check to see if any fault codes flag up

Lot of car for the money. Personally, I’d opt to change the oil every 6-8k miles. This will be a Tiptronic transmission 8-speed and generally bullet-proof, but again, if it were me, get the fluid changed. Yes, Audi will tell you it’s sealed for life, but ZF who make them have a service kit. Turbos, your guess is as good as mine. Don’t hammer it, and if you do, make sure it’s warmed up.

Great job!

Hi ALL I have an Audi 80 Cab (1999) (1.8 ADR) and have a warm start issue. I have systematically gone through all parts on the injection system (MFC, Hall, knock sensors, pump, filter etc) and electrics. Appears to be starved of fuel, the next plan is to inspect/replace injectors. Appreciate any thoughts, I have health stock of bits and happy to share stories, I own her for about 20 years. Thanks John

Not sure changing tyres will make that much difference. I think the car lacks insulation. I did try stuffing the boot well with towels to see if it helped - it didn't. Lack of insulation combined with low profile tyres is the cause I suspect. I had forgotten I was still on this forum. I'll be leavinfg it now. Good luck.
