Gary, wish I had the answer, this is just to say my 96 Audi just started the same problem today. The first stage operates, but when it's time for the stowage lid to lift, it stops, and like you it still sounds like the motor is running. If this helps, there is a reservoir under the motor in mine and the fluid level is ok, but how to top it up isn't obvious. Can't get a haynes manual for mine? If any one has come back to you I'd be glad of any tips
