Hello
Bought an 02 Audi A4 1.8T 3 months ago and love it.. Now, when I go into my garage to start it every morning, I notice my break lights on... This happens every night now. I check my breaks before I shut the car up for the evening and they are off.. But waking up, they are on and the car will not start due to a 3/4 dead battery. WHat could cause this. I noticed that I am missing a bulb in the taillight, would that cause this?
Also, how can i reset the service warnings and cautions. The one's I am talking about are the once you see when the car is in park and you press the wrench button.
Thanks!

 

Also notice that my power windows and sunroof dont work. I checked fuses and they are all ok. All I did was refill the coolent res. and then wash the overspill off with a little water. After doing that, everything was still working throughout the evening.

 

Figured out the light and windows issue,... Fuse in wrong spot. Believe I figured out the brake light issue as well.. Bad brake light switch on break peddle...

 

How do you know it could be the brake peal or switch?

 

because i tested with another switch, and now my lights are on all the time... But, my battery keeps draining... Would that be cauz the switch has failed and my abs and traction control or thinking they are failed?

 

put a new switch in, maybe that'll stop draining your battery. I don't believe the switch is tied to anything with the ABS and ESP.

 

This is Solved... It was the switch. Evidently the bad one was not completing a circut and causing the battery to drain, no matter what fuses I pulled.
