YOU HAVE BEEN WARNED.
If you are having any issues with the brake lights or symptoms of Cruise control not disengaging e.g. when you press the clutch, it may be as simple as a switch not working any more.
The switch output from the brake, clutch and cruise control stalk can be checked via VAG-COM.
Select Control Module
Select "01" Engine
Select "08" Measuring Blocks
Select Block "066" and GO!
Display columns 2 and 4 show binary switch outputs from the
Clutch/Brake pedals and the Cruise control stalk, when you press the pedals or
operate the switch, the 0's should change to 1's or visa-versa.
The change indicates a working switch, if no change occurs you can isolate the failing switch.
