I would suggest getting it to the closest transmission shop or Audi dealer as soon as possible. Any error message is not good and driving with an error message is never advised.

Sounds like your reverse gear sollector has worn-out

Speedometer problem: This is well-documented on V8 and 200 models..Check here for info:

Dash lights: check the dimmer control knob first, then the bulbs..If not those, then it could be related to the problem above...

Driver's seat warmer; could be broken wires leading to the warmers inside the seat from, or the elements are simply burned out.

Blue smoke is oil related, not head gasket (which would be white)..Most V8's will exhibit a little blue smoke from time-to-time, but if it is excessive then it may be time for vailve seals or piston rings..depends on the mileage.

If I understand you correctly? You may have a plugged filter. Try servicing the trans. EG: Trans filter kit and good quality fluid that meets or exceeds Ford specs.

On the side of your transmission will be a switch with several wires coming out of it. This is your reverse switch that turns on your reverse lights and most likely needs to be replaced

My story Dealing with Dodge

I had a 1994 Dodge Ram. The Red Dodge Ram I had it malfunctioned and my brake became the throttle. I had to put the truck in reverse then park. to stop, after it was out of control at 80 mph a hill slowed us down. Are you sure its not electrical and the curse control is not giving you trouble? Mine had multifunction switch was not working and the headlight switch burned up. I also found out that Audi had problem with the brake becoming the throttle in the 1980s Daimler Chrysler and Audi were German made. I don't think there is an easy answer. I hope you stay safe. Another man is having strange trouble also. I'm sure there are many more people with trouble with the vehicles. I wish Dodge would step up to the truth. and recall their nightmares. I saw many of their 1996 Dodge trucks at their dealers shop with all the electrical pulled out.
