1. The pedal switches ground the circuit, IIRC. No power there. Switch
could be dirty, by the way.
2. "Grounds are good" maybe not. They may not handle the current very well.
3. How are the rest of the taillights? Do the signals work well while
parking lights are on?
4. Don't be afraid of the wiring. Dig out your Bentley, and you are
pretty much just following one or two color codes around. The schematic
will show you what voltages to expect and where, under various conditions.
Here's something I wrote long ago about VAG taillights:
