Just booked in my MY12.5 GTI to have the clutches replaced. Have been complaining for previous 2 services but they came back saying operating okay. It has just gotten unbearable over the last couple of weeks. As it comes out of warranty next month, I thought I had better do something. Took someone from the service dept for a short drive. Having worked out how to make it shudder on command, drove about 20 m up the road and he said yep that's it. No problems. No argument.
All booked in but just had to wait for a loaner to be available for the 2 days they need to fix it.
