We had a similar issue with our 2003 A6. In our case, the problem was the
brake light switch. Clearly, YMMV.

Every morning when I walked out to my garage I found the car's brake lights
were on. They definitely weren't on the previous evenings when I parked the
car. Depressing and releasing the brake pedal turned them off.  Figured that
the problem may have been caused by the particularly cold weather we were
having - and the problem did disappear last week when things warmed up.
Unfortunately it reappeared this morning and it wasn't particularly cold.
Anyone ever experienced this bug? Only thing I can think to do is replace
the brake light switch.
