Fuel door locked due to central locking failure, how to put gas in car?
 

My central locking impeller failed when I locked the car last, already determined cause and ordered a new impeller. But my fuel door is locked and I don't know how to open it. Car is a 99.5 A4 1.8t quattro.

You have to pull back the felt lining on that side and pull the plunger towards the back of the car

Where did you order a graphite disc? Or did you buy the entire motor to replace? I’d like to find a source for them if you did. Also be aware, the reason why they break is because the vanes that slide against the wall get shorter and shorter and once they become too short, they jam against the wall and break the disc, shattering it.
