1. Step on the brake pedal...release....and motor/sound near passenger rear seat engages door locks.... they simply response to the release of brake!?

2. Fuel gauge and temp hardly work...sometimes not at all.

3. Car would turn over today but would not start...no problems up to this point with engine.... now it is stuck in a parking lot....will not fire up.

4. a/c,heat fan speed control **** does nothing on any speed setting.... it seems to be stuck on the lowest setting....a/c blows cool though.

Any help would be appreciated...in the course of 1 week my new(used) Audi did this....my Ferrari is making a really bad valve noise...my Porsche 944 S2 water pump went....the only car that works is my Honda CRX race car...not street legal... HELP.

Car is a 1994 Audi Cabriolet.

Best Regards,
Christopher
