fuel cap wont open?? cold weather maybe

[R55 MRU]

Hey guys. my fuel cap wont budge i press it inwards to release the popper but nothing happens. cant get it open atall. dont want to pull it and force it. anyone else had this problem atall? could it be due to the cold weather. as the whole car has got frozen ice on it. maybe the popper has frozen?

Yeah guaranteed mate! Happend to me a few times in bad weather last year. Give it a tap, if that doesnt work squirt some de icer in the gap! Worked for me.

There is a manual release behind one plastic black popout halfway up in the luggage compatment on the right hand side. When you pop it out there should be a red coloured plastic rod that you have to pull to release the locking pin on the fuel flap.

cheers for that guys. Learning new stuff with the car day by day.

But be careful the manual release could break something if you pull too hard if it is frozen. Never tried mine so not sure but would not want you to damage it.

humm personally i wouldnt like to spray deicer on paint work, rather get some hot-ish water and use that instead

Didnt he say the fuel cap, not flap, hot water as its a sealed hole with the cap anyway, so wont go into the tank.

Also if the flap solenoid is frozen, dont pull the red plastic as it will potentially snap & then when it truly is busted in not so cold weather you're fecked.

Afaik you cannot push the fuel cap to open it so it has to be the flap. Depending on if he's desperate to refuel, he can choose to pull the tab or wait for it to defrost. Hot water is a good idea but solenoid is mounted on an inner skin which means he'll need lots of it.

He seems to be confused as to which is which, but yeah I'd agree it would seem he has got issues with the FLAP, maybe he can clarify this so we're not at cross hairs.

He could always pee on it, depending on his previous evening it may also help fuel the car but I reiterate, if its frozen stuck, be very careful with the plastic release piece, as its not that strong trust me, as had that area of several 8P's many times.

I found when my fuel cap got stuck it saved me nearly £50 a week. I have now permanently disabled it with vagcom.
HTH

Hi Paddy,

Could you please tell me how you disabled? I have the opposite, never locks. Dealer has changed the motor, canbus and convenience modeule but nothing. Fortunately all under warranty.
Perhps I can enable it as per your instructions.
thnx in advance

Klik - I think Paddy was making a joke !

What he means is - because his petrol cap was stuck, he couldn't put any fuel in, thereby saving himself £50 a week ! :thumbsup:

The Vagcom comment is also a joke ( I think !!!!!! )

Get the dealer to check the wiring, it a reverse polarity circuit iirc, a simple multimeter test on the feed wires as its a pulse signal, so if it isnt getting a pulse when locking/unlocking on either wire, then they need to work backwards to the point of each wire connection, it should just go back to the conv module tbh so cant see there issue in finding the fault.

Thnx NHN,

Through dealers VAS, the cap was locked but when we tried with my remote key it stayed locked so we had to unlock it through VAS again.
They have ordered the drivers window module saying that some signal wires pass from there.
I will let you know how it will go.

cheers

Our Loaner A3 SB will not shut... any ideas? It is minus 3.5 degrees here at moment!!

The conv module locks the pin across, the signal from the remote is sent to the conv module not the door module & then the conv module signals the door modules to lock or unlock, now if you used the key its a different story as it has loads of microswitches inside to signal the door module, but its just a signal from drivers door to the conv module which then signals the passengers & also tells the rest of the car modules that are interconnected that the drivers door is also locked or unlocked.

ATM I find it hard to believe the door module is to blame cause the rest of the car locks if I read right, but knowing modules, they can act very stupidly sometimes.

sorry guys. its the flap not the inner fuel cap. Seems okay when the weater is not so cold. but at night and first thing in the morning it wont budge
