I've just had the cambelt changed on my 130PD

The car used to be silky smooth from 900rpm up but now there is so much vibration I can't bear driving it below 1,500rpmm and have to keep it on boost the whole time - real pain around town its ruined the car.

Anyone know of particular problems or sensitivity to engine mounts to have caused this. Above 1,500 its prety smooth again so I 'm presuming that the timing is right?

you need to return the car to the person who changed the belt ,as they haven't got the pump timing right , and this can leave you with big problems

diesels need to be 100% right ,and you need the correct tools to do the pump timing / lock the engine in correct place etc. , not a job to take on unless you know about diesels -

also ,would suggest that you always fit a full cam belt kit ( I work for a firm that makes them ) as its not the belt that goes , but the tensioners

also look at the bottom of the engine to see if the middle bolt holding the sintered

pulley to the crankshaft has been tightened up ( though you dont need to remove this to do the cambelt , sometimes it can come loose )

Its had the full kit of genuine VW parts

Is pump timing an issue on PDs?

yep , all diesels need to be exact with the pump timing or they either smoke ,or give other problems
