Hi all, and happy christmas
Ive got a 2002 2.5tdi with an acv engine and today it started to run lumpy on idle,and after about 25 minutes of it being turned off it took about 15 seconds to start, which is un usual for my van, had a quick look and it seems as though a diesel return pipe is weeping a bit, does anyone know if the slightest leak would cause these problems or do I need to be looking at other possible causes (maybe an air leak) as it does seem to have a little bit of a different whistle to the engine now. (it has got pp injectors, remap and k & n kit and decat freeflow exhaust)
I am going to put on vag com tommorrow, but any suggestions welcome.
Many thanks Matt
