I don't know what the Electronic Stabilization Program does, but lately I've been having problems with Acceleration and if i'm driving for example going 65mph on the freeway, it will slow down by itself without me stepping on the brake pedal, then after 2-3 secs it goes back to normal and accelerates just fine. I don't even know what it is. It's starting to **** me off because problems just seem to pile up.! please help.
I have a 2004 A4 1.8t Quattro

Also the brake lights come on by itself at night. I don't know if it's the Brake Light Switch or the light itself and if the Eletronic Stabilization Program has anything to do with it. :s
