Great car and built really well - great carrying capacity + all weather grip - esp up here in NE Scotland - we've just had 2 of worst winters in last 20 yrs - lots of snow + ice - car came into it's own.

However this am - I experienced longstanding injector issue - dashboard warning msg "Engine Fault - Garage!" + total system shut down - my car has full VWSH - 79600mls from new; car recovered by AA to local VW agent (who's looked after my car from when I purchased it) - Service Mgr said VW know of fault and are replacing injectors + wiring loom FOC. Due to parts availability/del'y issues car will be with dealer for 2 add'l days.

My question is - according to service records - the car is due to have the timing belt changed at 80K mls - will this be done when they change all injectors + loom? or as the head is off to facilitate injector changeout - if I suggest they replace timing belt at same time - what should add'l hours/charge be?
