Nor can i but they have VAGCOM - Remap software so the thinking is see whats going on by driving like a fairy up and down the street to check boost pressure etc. i'm leaning towards N75 valve as the actuator has been tested by the reconditioners apparently. I'd like to check myself without shelling out even more cash but i don't know anyone nearby with VAGCOM to borrow. Basically if its something serious and going to cost more to fix then its the end of a 13 year era i think. i'd get more money breaking it? funds are depleting..
