Hi, I have a T4 2.5 TDI 888 special on a 53 plate. The cam belt snapped (even though it was apparently replaced less than 20,000 miles ago according to the service history). The local commercial Garage has done the repair for me, but a tapping noise still remains, and when I drove it it seemed under powered. They have it back to look at the hydraulic tappets, but there seems to be another problem. I love my van but this could be the end of a beautifull relationship. Any one got any tips or hints I could give the garage? even the good guys need some help every now and then.
