I have just purchased the Audi, and it has a few flaws.
The exterior paint has begun to ware on the driver side c-pillar. And some surface rust has developed along the rear window edge and the rear bumper edge.
The electrical system seems to have some faults. (i.e The radio and door bell stay on after the battery is connected and the key is out of the ignition slot)
The clamps that secure the exhaust pipe rusted and have cracked apart.
After a heavy rainfall I have noticed pools of water accumulated within the front foot wells, and the spare tire storage compartment.
The driver side window has fallen off its track into the door. (It seems as though the power mechanism is missing)
I absolutely love mine! Its extremely comfortable!
It handles well, and runs quiet, smooth, and solid at any speed.
The heated seats, power sunroof, and key light are all such wonderful bonuses that come with this car.
The engine runs smooth, at any rpm, and has a very linear acceleration style (not jerky at all, very smooth)
If anyone can help me figure out the issues with the window, water and radio/electrical problems it would be greatly appreciated.
The 1990 Audi 100 is a phenomenal car, and I would recommend it to anyone looking for a solid, well built and stylish older alternative to the Mercedes-Benz E-class, or BMW 525i.
Well on my audi the window fell out also and I just used rtv blue gasket sealent and put it back in its track. it is really easy to see where the factory glue failed when you take apart the door handle to put the rtv gasket sealent in the groove. oh yea and get your thermostat and timing belt changed as soon as you can afford to becuase when you have problems with those your car is junk and you should just prevent it. I wish I did becuase I am currently waiting for my cylinder head to comeback from the shop because of those two problems I mentioned above.
Concerning the radio/ key beep this is normal. Audis and Volkswagens from this era would allow you to listen to the radio after the car is shut off and key is removed. Then, if you open the door while the radio is on, it will beep to remind you. Simply shut the radio off, and the beep should go away. A useful feature I think! Also, it will allow you to use the power windows and sunroof for about 10 minutes after you shut off the car. When you open the door, a relay will click that shuts those features off.
