Thanks all. Well, in spite of my ranting, my faith has been changed in at least the RAC this morning.
Fault diagnosed, its a coil pack. But the car would not start at all last night and all morning.
RAC guy has been an absolute star. Drives a black Edition 30 himself.
Has diagnosed the fault, but offered me 3 options.
1. Fix the part, and charge the cost.
2. Recover the car to the dealership.
or
3. Call VW assistance, see if they will come out and replace the part under warranty.
He really didnt need to offer number 3, and has gone out of his way to call back to RAC headquarters, and get one of the VW assistance technicians to see if they have the part on board, and if not, pick one up on the way and come and fit it.
So at this stage, it looks like we should have it back up and running in the next couple of hours.
However, im still not happy with the gearbox, and will be getting it booked back into the dealership asap. When the gearbox is hot, it still has the mechatronics/clutch related symptoms.
