Default Fuel door problem

Anyone else experiencing an issue with the fuel door? Whenever i pull into a station the attendant cant open it. I press the unlock door button over and over an nothing, only thing that works is closing the doors locking the car with the key fob and unlocking them again with the key fob. Annoying as hell. I'm gonna have to take it in to get it looked at.

The only problem that I experienced is that fuel door is difficult to open during the winter; a few nights ago, I had to spend several minutes scraping ice out of the crevice between the fuel door and the surrounding body panel before I could get the door open. I never had a problem getting a traditional door open during the winter.

Using some spray silicone on the latch mechanism keeps it from sticking in cold weather. Works great on door seals too.

This happened to me once at the gas station. I had to restart the car and then turn it off again to get the fuel door open. Since then, I've seen the error come up one more time in a VAG-COM scan as an electrical fault to the fuel door locking mechanism IIRC, but I don't remember having any issue at the pump.

The issue's not reproducible so I didn't bother having the dealership look at it.

same issue here except mine won't even open at all after re-start and etc... Ended up using to manual release at back of the trunk (see manual for detail). First real issue on my B8 but a very annoying one. Scheduled to a visit next week to the dealer will see what they say.

Don't clear the fault codes. I had the same problem with my fuel door not unlocking. Took it to the dealership and they replaced the fuel door release servo under warranty.

Make sure the key is in the ignition and the car in in "P"

Ya in hindsight I should not have cleared the code but I was tinkering w/ VCDS and wanted to get a baseline readout w/ as few error codes as possible (I don't have my Sirius activated so that always comes up in the scan). The next time I see the code, I will probably leave it and take it in for them to see.

I've seen other B8ers report this issue as well; could be one of those B8-specific issues that have flown under the radar and haven't yet been addressed.

Silicone or vasoline work well on this.

Where the heck do you live that has a gas attendant? Haven't seen one of those folks for years.

They're still required in NJ and I know they were in Oregon at one time as well.

Just got a 2009 A4 and am having the exact same problem. The owner's manual says the fuel door should unlock when the doors are unlocked, but ours seems to only unlock with the key fob. It does NOT unlock with the driver's door unlock button. Ours has the advanced key feature, for what that is worth.

Has anyone figured out how to fix this issue?

There are a couple of full serve only towns around me and I don't recall ever having to unlock the car to get the fuel door to release (unlocking the car sounds like a safety issue to me). I've just pulled up, shut the car off in park but left the key in the ignition. Taking the key out would open all doors and the fuel door as that is how I've set the car (unlock all). I know taking the key out works for me as the fuel door keeps opening when I hand wash the car. Something to keep an eye on though based on other posts here.

In our case we have the Advanced Key, so the key is never in the ignition. I also have the car set to Unlock All, and that works with the doors but not the fuel door. The beauty of the Advance Key is you can keep it in your briefcase or purse and never need to pull it out to unlock, lock or start your car. It seems to defeat the purpose to have to pull it out when you fill up with fuel. Even so, why wouldn't the unlock button on the driver's door work to unlock it?

Ah, ok, I understand the problem more. Sorry I misinterpreted things. Sometimes a manual solution is so much easier. At least we have a lock. I'm amazed at how many cars out there still don't have a locking fuel door. Good luck advanced key users w/ this problem.

Default Fuel door

Had the same problem with the fuel door. At first I just cycled lock/unlock with the remote and checking each time until it opened. This is in Phoenix at a temperature of 65F so there was no freezing. Sprayed the locking device with WD40 and it now works for at least 4 months. It appears that the plunger needs a little lubrication.

Been having this issue very frequently lately. Glad I found this thread. I'll try living the lock and report back in a few weeks.

I had that exact problem. Replaced the fuel door positioning motor. Their scan showed a code short to ground but that went with the new motor.
