I have a 2001 VW Passatt 1.9TDI 130BHP that is leaking oil from the various joints between the Turbo Charger and Intercooler. It has always leaked oil from the joint above the Intercooler depositing oil onto the inner wing, I am told this is common. It has started to leak a fair amount of oil from the joint next to the Oil Filter and below the Intercooler. My concern is that I am told that there should not be any oil in this pipe and therefore there must be a leak into it from another location. Having looked at the Haynes manual, the only point that oil could enter the system, is through the Turbo Oil lubrication Pipe. Should I be worried about the oil leaking from this pipe or is this considered normal?
I would appreciate any advice, you guys could give.
Many thanks
