Horrible acrid white smoke, at idle, no misfire, I feel a bit silly posting this but the owner is in a hurry and everything is difficult to access
anyway no fault codes, using kts live data seems a little hit and miss no fuel pressure reading it thinks it has three lambda sensor one of which is reading 320v yet no faults so i have been ignoreing the information provided.
carried out a relative compression test with pico every cylinder looks good
checked egr opperation appears to be doing what it is told and not sticking,removed air boxes filters are new
in live data it has an exhaust pressure reading yet i can not see a dpf it does have a bit of a hiss when being reved up the pressure in the live data says 2000hpa on light throttle seams a lot, can not find pressure sensor and the exhaust was fitted before the rest of the car so before i remove it has anyone any suggestions
the longer it idles the worse the smoke gets, after a short drive the smoke clears until it idles the re appears immediately, starts smoking from cold and it is definitely a fueling issue
i have yet to test the injectors for leak back(how do you remove the pipes without braking them)I also have not removed them and tested them as obviously this could be a low pressure fueling problem
here is hoping someone has seen this before to save me several hours of removing an exhaust for no reason
Thank you
Graeme
