Just thought I would enlighten the members on my complications today! I took my 2.0 tdi to the garage a few days ago for a cambelt change and mot, I hadn't heard anything so went to check on it today! When I got there the car was in a bay with the bonnet up being worked on by the mechanic! I spoke to him, and he explained how lucky I was! basically wen he went to take the tensioner off, it undun with his fingers... Castestrophy avoided in my eyes! as I stood there relieved he then went to put the new tensioner on, it didn't tighten.... :/ this means the thread has gone in the head... Has anyone else had a similar experience?
