I've been trying to locate this thread on various forums and I can't quite find it. I remember reading about S4s having a weird problem of blinking headlights/fog lights during a car wash. I experienced that today when I was rinsing my car off. I just wanted to find out if anyone has figured out what causes this and if it's a problem that I have to look into. Any help would be greatly appreciated.

 

That happened to me (A4) one time while I was dusting it. Not sure what caused it, though.
