my 2006 golf gti (200T) dsg has developed aircon fault, first it was intermittent for abot 10 minutes, and then permanently wont work. garage refilled it (just a little needed,)and checked pressor sensor and pump and diagnostic say all was ok, but still it does not work, thinks the expansion valve may be stuck. At same time the speed control is intermittently not switching on (but has been erratic for months). could there be any connection between these two faults. symptoms of aircon not working remain permanent even when cruise control is working. It's a mystery. Garage initially suggested need new Intake manifold throttle body (approx £350) and that this may fix both problems...seems to be stretching the idea..I thing it may just be a computer problem!
