D4d Engine Fault

Recommended Posts

If the EGR valve was blocked, it is likely the entire iinlet manifold is badly gunged up as well.

OK gents. Replaced the MAF and VSV sensors. not much difference. cleared the P0400 fault and it came up within ten minutes of driving. Took the EGR valve out. It was stuck open app 1mm? Stripped and cleaned. Working ALMOST OK. At high revs on light but especially heavy load, there is still this "mild" misfire feeling. I think I'll let this Archoil AR6400-D Pro PEA Concentrate Diesel Cleaner do it's work. Still got half a tank left from Saturday. I'll fill up with the BP Ultimate and see how things go from there as it still fells like an injector is not operating at 100% or at the same efficiency as the rest?
