Morning all
Looking for some help, my Passat has just developed an engine noise this morning coming from the belts area. It sounds like a rattling/knocking when the engine is idling, and disappears when given slight revs.
Timing belt was done 2 years ago including pump and tensioners. Only thing that hasn't been done to my knowledge is the drive belt tensioner. My initial thinking is possibly the crank pulley?
I can't take a look yet til its a bit brighter outside, but could do with any suggestions on where to start.
