low fuel pressure, the bucket that the high pressure fuel pump runs off the cam wears out on the tfsi probably the same on these , timing chain stretch, carbon build up on the back of inlet valves, faulty fuel injectors, just a few of the problems that the modern reliable vw engine has. poor fuel quality , any diesel in there ? stick it on a gas analyser the hc goes through the roof when the injectors play up . |
