easy remedy. Mostly, if you get the car to a car wash, the guys and girls there spray plastic cleaner all around, so some gets into the stalk. Cruise control appears dead. Spray alcohol (lots of) right into the stalk, all excess alcohol drips down, and takes with it the isolating plastic cleaner. Spray a bit of WD-40 into the stalk to prevent corrosion, but PLEASE make sure you do not get WD-40 all over the interior of the car. Cover it up. And voila, the cruise control works again. No Audi fault, no "weak Audi Electronics" - just crap buildup that makes it stop working.

although i see what you are saying, but I've never seen anyone that actually tries to clean the stalk.... dashboard, windows, stereo maybe.. but the stalk???

and according to you the "build up", must require someone spray chemical directly at the stalk. its just hard to imagine any significant build up can occur without directly spraying stuff on the stalk... and which i seriously doubt anyone does spray stuff on to the stalk.

you do not live in Silicon Valley. Here the car wash boys & girls spray all kinds of crap literally everywhere. Onto the leather seats, the steering wheel, and right into the turn indicator and the windshield wiper stalk. Into cassette and CD slots for radios, into switches, everywhere. I do not know who told them to do so.
