Trying to diagnose cruise control not working on my 03 RS6.
It doesn't work any of the time and never engages.
Here's what are the options that come to mind:
* Brake light switch
* Control box
* Steering wheel stock
So, here's where I am:
* if I press on the brake pedal, the rear brake lights turn on, so should I rule out the brake light switch?
* I am able to start the car in park without pressing the brake pedal. Is that normal with other RS6s or C5s in general?
Thanks,
Chris
