When I got my MK5 I looked at cam belt change in handbook, oh its a gt tdi. I had a Mk4 gt tdi for 10yrs previously and it was 80,000. Now the Mk5 handbook stated 100,000 , so I thought that's good they have increased it. But on checking with dealer, it had gone back to the MK4 5yrs 80,000 miles.
So I'm guessing VW changed their minds and went back to shorter mileages after some failures in the real world???
