Mostly going up hill, when I have the car in cuise, it is pulsing. on off on off. Anyone ever had this? Causes?
Of course uphill the engine is under load. I guess it could be a multitude of things given how many sensors cruise control takes an input from. Best thing is to get a scan done and see what transpires from that first. Best to clear the codes having noted them down, then go for a run ( with cruise on!) and re-read the codes.

If you don't have access to vag-com then post up your location and some kind soul might offer to read it for you.
