Hi

Not sure if this post should really be in here or in the A6 section?

My P reg 100 based A6 2.5 5 cyl diesel auto estate has suddenly started running rough and being very difficult to start yesterday, after a motorway run when it appeared to be running fine. On arriving it was making a rattling noise from the front of the engine. Had it recovered home, the AA man thought that the pump drive belt had slipped but I cant really see how it can, and on inspection all the marks seem to line up.

Cam belt seems fine although I knew it needed doing when I bought the car. Is it possible to check it without stripping the front of the car down?

Any other ideas gratefully received!!!

hi
the 2.5 tdi has two belts one at the front one at the back of the cam shaft this one gets overlooked and may be your problem . i recomend replacment of all belts, tensioners and idlers in one go also fit a new water pump as thease have a habit of failing once disturbed.
hope its of some help
