Now, in order to get the sunroof to close, I have to hold the little
wind spoiler down, otherwise the motor can't handle it. Is this to
be expected at this age and mileage? Is a new motor inevitable?
I had this problem on my previous car, an '88 Audi 80. It started at about
40K or so, and looked to me like the motor was slowing down. The dealer told
me that a good lubrication (WD-40) of the guide rails will bring things back
to normal, which worked perfectly. I found that I needed to relube every
5-10K or so when it slowed down after that.
