hi, bmw service technician arrived today,scanned with malfunctioning GT1 but managed to get fault code for left front wheel sensor,AGAIN, I am seriously angry at bmw for refusing to replace sensor last time, they have been warned what will happen to them if car causes accident,so now they are very humble, car is at new dealership run by top company,they will replace sensor tomorrow, hoping car will be ok as it is excellent driving machine for something akin to a van,handles corners better than most things on the road, had V10 toureg on my tail for 10 miles of A41-whitchurch other day -man they wallow and wander badly, and i was loaded to max,vw could not stay with me on corners and i was cruising comfortably,i shall post result of dealer visit.
