It's a 1998 A4 1.8 Quattro. First, they thought it was the switch, so
they replaced that. Test drive was fine. Next day, blown fuse.
Yesterday they spent 3 hours ($$) examining the wiring. Couldn't find
anything wrong. New fuse in, test drive was great. Today, blown fuse. I
replaced it, drove around, tried everything I could think of to make it
blow (turn indicators, power locks, stereo, A/C). Working great, but I
know I've got about 24 hours before it goes.
If anyone has a suggestion, I would greatly appreciate it. I'm at the
end of my tether. The only solution the service dept has (re-wiring)
is so horrifically complicated and expensive that even they don't want
to do it.
The only other issue I'm having, but this has been going on for many
months -- long before the brake light problem -- is the cruise control.
It works about 60% of the time. The rest of the time it won't engage,
or engages for a short period and then cuts off. Temperature and rain
don't seem to play a role. Happens in the dead of winter and during hot
summer days. I can live without it for now. (I mention it only in
case it's relevant.) But brake lights are serious. I actually found
out I had the problem by having a very angry motorist yell at me.
If it's relevant, I live in a climate where the winters are very cold
(-40C is common) and the summers can be very hot and humid.
