I have a similar intermitent problem with my car. I have a 96 A4, I think
their locking systems are the same. (Feel free to correct me).
First thing first though:
For your biggest problem, the fuel cover being locked, that is surprsingly
easy to solve. Open the boot and take everything out. Also take out the carpet
that covers the spare wheel.
Then closest to you, where the boot closes is a plastic decal. There are
button head screws in that on the inside verticle. Take allthose screws out
and remove the plasitc decal. be gentle with it!
Next on the side where the fuel cover is, remove the "carpet" wall. There
should be some more screws holding this in. They have the same surface finish
as the wall so well camoflaged. Use a good eye to find as many as you can and
remove them. Then VERY gently peal it away towards the centre of the car. If
it won't come, find the point of most resitance and there will be a screw you
Behind there should be various pieces of sheet metal and a few other do-dah's.
What you are looking for is what looks like a poice of wire coathanger running
towards teh front of the car and slightly off horizontal. (Been a while since
I've been in there, I can't remember if it is hiden by some sheet metal or
not) Anyway, you want to find this wire and gently pull it towards the back of
This wire is attached to a pin which locks the fuel cover. If your central
locking system has truely failed, once you have done this, it will forever be
unlcked until you push it back, or you fix your central locking system.
Second thng, diagnosing and fixing central locking system.
While you were doing the above, you may have noticed a wierd solid pump
looking thing in the bottom of a well. Much like where the spare tools are,
but on the other side of the car. This is the heart of your central locking
system. When you lock your car, it whould whir as it blows or sucks (it does
both of these regardless of whether it is working or not, just different
defnition... hehehe...) Oh, yea, your whole locking system is probably
pneumatic. Another check it to disconnect the tubes running into. out of it
and blow/ suck on them - to check continuity of the pipes.
If it whirs then it is not an electrical problem. If it doesn't, try a
multimeter to see if the pump gets a signal. It probably will, and it will
probably be your pump, replace it and pray.
If the car doesn't unlock/ lock as you blow and suck on the tubes, you
probably have a leak. I would recomend having a close look at the doors areas.
Again replace any tubes you suspect leak and pray.
If the pump gets no signal at all, it could be a broken wire or it could be
some electronics somewhere in the aether of your car :(
