Fuel tank lid door does not open on 855 TDI

855 TDI 1997. After a few days with freezing temperatures I wanted to fill the
2/3 full tank. The door over the lid did not open. The car´s manual explained
how to get access to the lever near the right back lower lights to manually open
the lid, I will do it during daylight time. But I wonder whether that has to do
with the low temperature? Or is it a faulty damper motor. I could not find info
on the VADIS or Haynes manual how to get access to the damper motor. How is it
accessible and how should I test electrically whether voltage supply and motor
function are ok? Could it have to do with manually locking doors?

Is it possible that the fuel door is frozen closed? When I lived in
more northly climes this was frequently a winter problem for me with my
old remote-open Ford. A bit of WD-40 sprayed all around the door plus a
couple of good thumps usually got it open.

 

Problem solved.
One really has to pull hard to get the floor cover off. The security device
causes more problems than fuel theft might cause. I think the time of stealing
fuel from car tanks is over in the EU...
