I have a 2009 Audi A4.. Took it to the car wash and had small leak in rear seat around the convertible top. (We just purchased this car 2 weeks ago)... Now the electronics are going crazy..the windows won't work, the dash lights are going on and off, the TPMS indicator is flashing, the airbag light is on...and it sounds like a "motor running" in the glove compartment...any ideas what the heck is happening?

 

It's hard to pinpoint the specific problem but considering it started to happen after you got the car washed it sounds like something is wet. Either some of the connectors or worse case some of the computers. Is there any water still under the seats or in the trunk area. Does the car still drive and if so what works on the dash.
