Random current drain
 

Like several others, I have a problem with intermittent current drain on my car (Audi A4 1.8, 2000-model).

I've measured the current to 0.3A, and isolated it to the circut for fuse 15, controlling instrument cluster, power windows and climate control.

Have anyone experienced the same problem and have any suggestions to what is the most likely problem? Also, is it possible to test further without dissasembling the entire dashboard?
