'05 MKV Jetta. The rear side marker lights turn on with the headlights, but then go off after about 1 second and stay off.Why?
Rear light bulbs are burning out all the time. Wrong Fuse strength?

Fuses wouldn't have anything to do with it. They are either undersized, like a 5 amp in a 10 amp situation (they keep blowing) or oversized, like a 30 amp in a 5 amp use (car burns up).

Something is messing with your computer commands, I would remove and check the big ground wire going to your battery, and clean all contacts at either end prior to reinstall, first. Usually poor grounds are the reason your computer starts going bloooey. Try that before anything else..
