I'm trying to help my mate out with a problem with his 2001 VW Passat 130PD. I know its a VW but your input is greatly appreciated.
After having a turbo blown and replaced he is having an annoying issue. When the car is started from cold, it plumes smoke and stinks of un-burnt fuel. Its surely a sign of over fuelling?!?
He has recently removed and cleaned the EGR valve, all the intercooler pipework, intercooler, and had the injector seals replaced.
He has also got all charge pipework checked for leaks. The smoke does not appear on idle when the engine is warm. No faults have apperaed on Vagcom either!
Could this be related to a cold idle system of some sort?
Any and all help is much needed.... my mate is a very stressed and unhappy individual....
