Audi a6 C7 fuel lid stuck

[Saim77]

Hi ,

I have a 2015 a6 Saloon (Ultra) , this morning when i tried to fill the car after 4 months the fuel filer lid wont open . Its just a push open and used to work like a charm before .
a quick call to audi and they are saying book the car and the whole unit might need replacing which i dont want to do .

any suggestions / help will be appreciated .

The black section and the opener are around 40-50 pretty easy diy, however if your cap is stuck you may need to pull the opener from in the boot.

There is an emergency fuel flap release in the.boot, look for a RED cable.
When you get it open, a squirt of WD40 on the locking pin might free it up.
It is a common fault.

Common problem, had it on both my C7s, caused by the actuator seizing. The emergency release does not usually work and the only option is to use a flat object to carefully force the filler flap open

Hi ,

That exactly what happen in my case , the emergency release never worked and it came off . Took it to IVS (huddersfield) and they managed to open it without damaging any thing . Now waiting for a replacement to arrive so that they can fit it . All in all £93 supplied and fitted which is better the Audi's 120 only to look into it .

Thanks for the response

Mind did this and the whole assembly has to be replaced its the solenoid for the central locking that fails in the locked position. My emergency release did not work, its a wast of time. I managed to get mine to release by applying pressure on the flap as you would to close it, keep the pressure on and cycle the central locking with the key fob several times hopefully it will release on one of them, mine did then you can leave it part open until fixed. try not to damage the flap as that is not part of the kit.

Hi,
Did you get it sorted,
Sorry just went on the site again and seen your problem,. I had the same fault a few months ago. seen something on YouTube that helped abit but to be honest I went at it blind . Got the part from a Audi dealer for £28. Drilled four holes in the black inner cover released it and fitted the new actuator. Took around and hour. I have pictures if you want to try yourself.

Happened to me years ago on a fuel station forecourt with a company pool car at 12pm. I did eventually find the emergency release, filled up, went to pay at the security window and found a very scared server. He had called the police! Turns out while I was messing around another car drove on to the forecourt, didn’t get fuel and drove off. 1+1=3. Of course I didn’t care to waste my time waiting for the police, left that to the server.

S77, I had same problem 18 months ago. Others have replied but my 2p worth is that I demanded Audi replace the fuel filler as I understood it to be a KNOWN fault. There are many references to it online. They did so FOC eventually. It's a shot to nothing especially if you purchased the car from Audi. Even if not... worth a try.

This happened to me a few years ago, press and no opening. I tried the emergency release - useless. I was extremely low on fuel, so called West London Audi and drove straight to them, explaining that there was virtually nothing left in the tank, and I would end up stranded. I left it with them overnight, and collected it next day. They fitted a completely new filler unit. No charge! The car was well out of warranty (2012), but I've gone to them to service this and my previous A6, so maybe some goodwill was in the bank.

I'm loath to say it's been fine since, as it will probably go wrong tomorrow, because it's a common problem.

I have the same problem this morning - my 2016 2 L Sline Ultra has done 31K miles. I eventually managed to find the emergency release cable in the boot. 38386 You pull the metal rod out of the clips and turn the clips 90 degrees to move the cover - be careful has the 12volt boot cable socket still attached. I then had to get my hand back up behind the panel - got the red release cable - pulled and nothing happened. Went down to my local garage - guy has not heard or problem before, so having read loads of threads about this being a soleniod failure and common fault, started to push and move a little the fuel filler when releasing central locking and it opened. It's now remaining open until I fill the tank later today, but can anyone advise how to remove the filler assy to get at the solenoid to replace it - I can see the 4 rubber lug type things - and have read you have to remove filler cover from outside. cannot find any videos on youtube. This picture - have put WD40 on Central Locking pin - it does seem sticky, the drain hole is circled blue, and on an A5 forum - saw a video with guy making holes on red cirled rubber parts and pulling out assembly. Don't know if this is correct though. 38387 Grateful for any advice. Thanks

ps My last service I got done at local garage - all previous done at Audi - and I declined the timing belt change offer from Audi - so thought about trying Audi Customer service but unlikely to get any joy there I don't think - although common fault does not seem to be a recall item.

This is probably the best youtube video I have seen so far Audi A6 C7 Wymiana zamka (siłownika) klapki wlewu - YouTube (https://www.youtube.com/watch?v=DR8MaynOp-A) - removal of the insert seems to be hardest bit of job - not sure how those rubber clips work. The override must have worked - the cap is now unlocked all the time and working, but will order a spare soleniod and change it out. Have found a couple of part numbers for my A6 - 8V0862153A or 4L0862153D - but I think the first one is correct for my car. That's the one I am going to order.

I fitted the new solenoid today - the old one - the solenoid was operating - just the plunger was sticking. The 4 clips - covered by rubber have just little clips that need to be forced away from body to release - came quite easy really - never took long once I had that done - should have taken a photo but forgot. Once you have the main part out - changing solenoid is 5 minute job. There looks to be like very heavy corrosion on the solenoid part - which is stopping the black plastic mechanical part sliding to the left to release the spring loaded locking pin at the top right
Given the solenoid is sealed and where it is located inside the rear wing - this cannot be moisture related corrosion - very strange

I did takle a photo once I had split the old solenoid - my mechanical release never worked either 38452

When we service modern VAG products (especially Audi) we regularly see a fault for potential failure of the tank flap and advise replacement before inconvenient failure. It is not a difficult job and the parts are not expensive except with some makes the painted flap is built in which suddenly complicates the issue. It will never be a subject of an official recall as it is not safety related.

Helpful thread!! Have this issue with my Q7 e tron at the moment. Ev charge port door won’t open. Happened a while back but only for a very short period while this seems permanent. Must try a bit of force to release it. Hope it works or I’m guessing it’s an expensive trip to Audi (unless I can argue that it is a common fault)
