Took it in yesterday, low behold the technician could not find a fault with it.
He did however loosen the gear linkage to see if that would make any difference.
Driving to work this morning it was exactly the same,
Have booked it in again for an overnight stay Thursday night for testing from cold on Friday morning.
Cant say that im to happy with leaving my car with them overnight but I will read them the riot act before handing my keys over.
Nice to know that someone else is experiencing the same thing.
VW have told me that it shouldn't be crunching, just hope that they can sort it out wiithout pulling the car to bits.
