Just purchased this 2005 audi a4 avant 2ltr tdi last week and im having a few teething issues!
The car has covered 81k with fsh and has had the head and oil pump replaced at some point but not at a dealership (guy who i bought car from owned a garage and done it themselves)
when driving in any gear,but only in low revs,upto 2000rpm, there is a vibration/rattle/knocking. Its hard to describe the noise but its only in the low revs when driving. It doesnt make the noise on idle or past 2000rpm!!
If your very gentle on the throttle it doesnt make the noise either!
I work at a vw dealership and have had the mastertech take a drive in it and he cant decide what the noise is but says its a "pinking sound"and it could be from being badly timed back up when the cam belt was done or it could be the flywheel (or something completly different!!)
Now with myself not being mechancally minded at all,im at a loss at what to do first, so wondered if anyone has had a similar issue or could help with any sort of diagnosis.
Thanks
