Thanks to mike foster, itwasntme187 and dave_ph, I have now retrofitted cruise control to my car. Audi quoted £399....I did it myself for £95. Thanks Audi! The CC as a function works, but the switch doesn't work as it should, and this is something mike foster is also encountering, as described below. SET button does nothing. Pulling the CC stalk towards me does nothing, UNTIL I press up (+) or down (-), and THEN CC is activated. It cancels when I push the stalk away from me, as it should, but flicking it back towards me does not activate the RESUME function. Again, I have to push the stalk up or down. itwasntme187 doesn't have this issue - his functions as it should, as depicted on the switch. Anyone else having this problem? I'm chuffed to bits that it's installed and working, but I would prefer it to work precisely as it should. Any ideas?
