Hi Steve, got 2 issues, thanks for responding. Firstly blew the front, offside injector out, bent the injector pipe and smashed the return rail. Ripped the threads from the head. Have replaced the injector pipe, and sorting the injector, hopefully! Secondly, even after 2 new injector return rails, one cheap, then a bosch, still don't seem to be able to cure the leak on the rear, nearside injector. Any ideas will be gratefully received. Thanks, Kneale

Thank you for the help, I will definitely change them asap, also will attach a YouTube link later for anyone wanting to listen, I know google d links are untrusted, totaly get you. appreciate it

Sorry Hamza, I will not open links to untrusted sources, however if the tyres are as bad as you describe I have no doubt they are the cause of the noise.

Thank you for the fast reply. Yes they will be 4 years now in July, they have some outer damage, like ripped on some parts of the outer wall and also on them there is damage on few spots, deeper ones and cuts. since it wouldnt let me attach a file up there I will provide a google drive link to the video so if you could check would appreciate it. thank you https://drive.google.com/file/d/1_sxytpyKlPQB4zKVt4Mzt4rWkFDFmclJ/view?usp=share_link

Is there any damage to the summer tyres, or a foreign body such as a stone jammed in the tread? Are they even at the correct pressure?

Have you read the entire thread? There are numerous helpful hints and suggestions contained therein.

Passenger compartment fuse box #1 (left-side) A5 (located 5th from the right)0)A Auxiliary heater control unit -J364- it should be the only 20amp fuse in that row. Since I removed this, my car only drains once a year instead of every week now. Still have all other issues like lights blowing out and MMI stuck etc, but this did help.

Hi there I have one of these for sale ,took it out of my Audi when I sold the car it the the BV auto one ,it is a good bit of kit but no use in my new Avant

Hello everyone, looking for help here, would appreciate it. Started hearing humming and grinding sound coming from the front of my Audi A6 C7 two weeks ago. Never had any problems with the car, clean maintenance done always on time, oil change, filters ect. After switching from my 18” winter wheels to my 20” rotors summer I started to hear this sound (will attach a video down if its possible) but not right away, 3 days after the wheel change. Brought the car back to the mechanic, they tried to see if its a wheel bearing problem but after rotating it, looking at it couldnt find anything, they said its good to drive but I feel it isnt , it sounds worse now then 14 days ago. The noise increases either speed, when you slow down from for example 90kmh down it makes like a jet noise haha helicopter noise I dont even know. Also you can feel a little vibration in the steering wheel and also in the gas pedal (automatic gearbox to mention), steering wheel is a little so to say soft when you go right but when you rotate left its more rought. any help would be appreciated, thank you!

Hello, i have a similar issue wherein the car will lower itself at the back after around 45 minutes of driving. Whilst not driving, the issue is fairly sporadic in that it could sit at its regular height for up to a week at a time and other times it will be slammed to the ground 10 minutes after I turn the car off. Issue is at both left and right of car. Any help would be greatly appreciated.

Afternoon all! This is my first post on this forum; nice to meet you all. Had lots of Audis in the past, but never a Cabriolet. Picking it up on Saturday. I do know that it needs a new plastic window in the rear of the soft top. I understand that usually the new screens are hand stitched in for about £300 at soft top specialists. However, I was wondering if anyone on the Forum had used Cristal Cabriolet. Their product makes use of the zip as per the stitched in ones but then has a 3m adhesive seal that you affix to the soft top fabric rather than stitching. I thought I might try this and then if the adhesive is insufficient stitch it myself using something like a Speedy Stitcher Awl. What are everyone’s thoughts on that? Cheers, Chris

Heather. There are a few companies who can repair your instrument cluster, ECU Testing being commonly mentioned here. They all require you to remove the cluster and post it to them. I forget the most recent price, but I know it was only a few hundred pounds, a fraction of the price of a new part from Audi.

Thanks very much for this response (just saw it now). Well...I've found that the battery isn't draining when it's connected to the car, and the instrument cluster fuse is removed, but drains rapidly when I reinsert the fuse. So that seems to confirm that it's that fuse, and presumably hence a fault in the instrument cluster. So my next step has to be to find a mechanic/electrical specialist to take it further. Many thanks to all for your advice.

Thanks all had a Couple of A6,s before and a Q5 really enjoyed them went away from brand but back now looking forward to collection.

Since getting the car in February, I've had a battery drain. I hooked up 2 batteries but still no joy. So, I noticed my mmi screen stays up and checking with vcds, there is a report of no control head adaptation. Thinking it was those gears, I removed the trim to find there is no housing at all for the mmi, it's been removed and the screen is somehow stuck in place. Had the battery checked, it's OK and the alternator is charging. Would a non closing mmi screen cause battery drain? Does it have to close to turn off the feature? If so, how does one go about having a different screen from a newer system installed? I'm just looking at getting a used mechanism to fix this or get one of those modern interfaces with a new screen. Thanks

Hello Steve, nice to meet "online" the man ho helped me indirectly to take a decision ( thanks to your guides in this lovely forum). If I can sell my Disco Sport during next week, I'll collect that A6 as soon as I can: the owner wrote me this morning, telling me that he wants to offer me for free an oil and filters change before collecting directly in Audi Service. The car, as far as I know, was kept always in a garage ( in fact, the car hasn't any body flaws or dents). I'll check as soon as I can the "battery drain" problem, as mentioned on one of your threads but i was in the passenger seat and the carpets doesn't seems to be humid or full with water. Again, if I can achieve to collect the A6, my next steps will be: Oil and filter trans change (ZF OEM parts) Distribution belts and water pump (Bosch or Continental parts) Full fluid change ( brakes, steering, cooling) Glowplugs (Bosch) Tyres (actually it has some good old Toyo Proxxes, but DOT 2019 and incorrect size, 215/55/17)

Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂 Check for wet carpets in front footwells which is often due to a broken pollen filter housing or blocked battery tray drains. This water can damage the CCM which is under the passenger footwells carpet. The CCM controls a lot of electrical functions so make sure all electrical items work. Looks stunning to be fair. Service history is key for the 2.5tdi. People say they're unreliable but this is often because people have failed to keep up on regular maintenance. My A6 2.5tdi had done 344k miles before engine expired. Regarding the gearbox, make sure it's been serviced and gear changes are smooth. Regarding the ingenium engine my wife has a Jag xe with this engine so fully aware of the issues.

Hi all bought a A6 tdi black line off norwich audi yesterday picking up on Tuesday looking forward to chats and information thanks.

Hello! First of all, I'm so sorry for my bad English: as an Italian, English isn't my fist language, but I'll try my best to be understandable. I'm a 33yo italian car enthusiast that especially bought english cars ( I still have as a "relax driver" a Daimler Six LWB from 1995). I also still have a LR Discovery Sport 2.0 Ingenium that is a nightmare (please, pretty please, avoid this engines like hell!!). Bought it used in 2021 with 68k Km on it and right now has 168k Km with over 15k Euros of extraordinary maintenance on it. Two weeks ago, while searching for new windows as I'm renovating my house, I stumbled across a 2005 C5 Avant AKE Tiptronic in marvellous shape. The car owner is the shop's owner aswell. He talked to me a lot about the car. One owner from new, it has 210.000Km made in roughly 20 years and only serviced in Audi. The car, in fact, was full of Audi invoices regarding some regular maintenance (engine oil, filters and so on) and some extraordinary maintenance ( distribution made at 168.000km in 2016 or 18 I don't remember, a new torque converter in 2018 at 189.000Km, tank diesel pump and so on). Actually that C5 is not used since 2022 because the owner bought a new Volvo XC60 and he wants get rid of it for 2750 Euros. The car drives smoothly with no esitations... Could it be safe to say that could it be a good car to make 25.000Km/year doing, of course, an oil change every 10.000Km and checking all the components when needed? Thanks in advance, I'll leave some photos of the car here! Cheers Federico

Hello there! I'm Federico, 33, from Italy! I'm in search of a "new" adventure buying an A6 C5 Avant. Thanks for help in advance!
