Audi 80 - electric sunroof stuck

Owdo

AS the title suggests, my electric sunroof became stuck last night in the open/tilt position.

Been able to park it undercover at work for the evening but, obviously need to get it sorted.

Have just spent £600 or so getting it back on the road after being in storage for two years (won't bore you with the details) so I'm obviously looking to avoid spending too much money on fixing the problem!

It's a 1994 model, 1.9 TDi saloon.

Have looked on the fuse box to see if that's what I need to swap but it seems to mention every other thing bar the sunroof.

Would it powered by some other kind of mechanism?

When I try the sunroof switch there is noise and the slightest of movement, so there's some life there but no indication that it's going to work anytime soon.

Will try WD40 and some brute force once again shortly but, if not successful, can somebody suggest an alternative solution?

cheers in anticipation,

Phil

Phil,

Your power windows and the sunroof are on the circuit so if the windows work then the wiring is fine and the issue is more then likely with the motor. If the sunroof hasn't been opened in two years the motor might be seized. Have a buddy hold the button in and with one hand on the roof and the other from inside push down and towards the rear of the vehicle as it hasn't moved in two years so sliding mechanism could be rusted together or stuck. Those motors aren't that strong so it doesn't take much. With some luck the motor will free up.

I had this happen as well as I was rebuilding the engine over the winter and the car didn't move for 8 months.

If you are able to free it up and get the motor to move open it all the way and soak it with fluid film and open and close it a bunch of times to grease up the sliding track and get the motor used to working again...

Garage
on some of these also, in the roof trim pannel (if you remove it) there is a slot for an allen key to go into to try to manually move the motor/roof, my 80 1.9tdi even had the allen key stored there also, when mine stopped sliding and was as yours is, i lubricated up all i could see, then i started to work the allen key bit by bit, from there it freed up, and when i got it fully forward and tilted i greased the rest, it worked every day required after that!

cheers guys - have just about finished clearing out the mess that was my garage so I can put the car in there and try some of the things suggested.

had to leave the car at work overnight the last few nights as that's the only place where I could guarantee it staying dry undercover - particularly after it decided to rain every day in Leeds since the sunroof became stuck !!

@weekend in whistler: the windows are manual, it's just the sunroof and wing mirrors that are electric (slightly odd I thought) but I guess the principle is the same.

once again, thanks for your time and I'll let you know if I have any luck
