hi paul, long time, i am one step closer to finish my car, changed the compressor and the valve block unit, hug different, quick into calibration height adjustment, but what is my problem now, it is going up and down, like there is no referance point for the levelcontroler to adjust, the ecu is changed, original number, the one in England was 4Z7907553F and mine is 4Z7907553G and its working, the new second hand ecu. no fault codes. how was your trip in norway, did you enjoy and what do you think of norway.
