Booked the treg in last week with the local dealership to get the tyre wear situation sorted. Dealership very helpful (loan car etc) but called me later to say they were not authorised (by V.W) to sort out problem and the treg had to be taken to a specialist technology centre even though the local dealership are authorised to sell and service tregs??? Treg has gone in today to local dealer who have given us a loan car and they are then taking it to the specialist centre. Bizarre situation altogether. Main wear is front passenger side tyre which has worn down on outer edge, should hear later today whether its the tracking (50% tyre cost) or the transfer box (no cost). Also trying to get wipers sorted out as driving me and the wife nuts!
