Hello all,
I have just purchased an MK4 02 PD130 after becoming a bit sick

of my mk3 GTI. The car has full service history but it is due one soon along with an MOT. Its my first diesel so I am looking for a bit of advice on what to replace to ensure the car runs at its best other than the usual service kit of filters & oil etc.
Can anyone advice any sensors, boost pipes etc that I will have to change eventually that I can do at the time of the service just for piece of mind. Some will say if its not brokern dont fix it, but I would rather spend a we bit extra changing small things when it is getting serviced.
PS: I know the timing belt is due in around 10k so thats already being though of.
Cheers
