Hey,

My A4 ESP always disengages randomly after about 10-15min in the car (orange electronic stability program light comes on when button was not pressed). Is this a common problem with 2002-2005 A4's?

 

i have a 2003 1.8t and the same thing happens to me, but probably like only once a week or so.. if you get it figured out let me know

 

I had this problem with my 2005 A4 Avant but I figured it was normal and never got it seen to. One day I noticed after parking the car and walking away that the break lights were on. I took it to the dealer (still under warranty) and apparantly my break switch was a bit flaky (this explained why sometimes when I pressed the lock button on the key chain sometimes the car did not beep, since it thought the break was being applied). Once the break switch (sorry not sure of the technical name) was replaced my intermitent ESP problem never came back.

I hope this helps.
