Re: Vauxhall Vectra C P2279 Intake system leak detected
Paul Emmott
Hi and thanks for taking the time to look at this one. Regarding testing the intake system to 2bar. I have modified my Blue point smoke machine by bypassing the original regulator and added my own adjustable reg. It does however slightly reduce the smoke density but what it looses is far made up with the extra pressure. This car is not a Dpf equipped car, but I have had another look today and stumbled across what I believe maybe the cause of the problem. During an extended road test I scrolled through the many lines of data when I noticed the Exhaust gas temp sensor reading of 576d as you will know this fig would be ok if the car was Dpf equipped and in regeneration mode. I suspect this could be the cause also of the lack of Egr duty cycle and the strange non specific error. I'm going to check this out in the morning and post my findings.
