I have a 2006 xtype 2.0d, I first of all had a egr problem, i did all relevant checks and found the vacuum hose was split going to the diaphragm, i replaced the hose, cleared codes and all was well, the car was running better than ever for approx 100 miles until I started to feel what can only be described as a missfire under acceleration, no eml though, the car seamed to run ok around town, later that day I was back on the motorway, as I accelerated from 50mph the coil light started to flash, I came off the motorway at the next junction and the car cut out, I started the car straight away and the coil light stayed off but it was running a little rough but I managed to get the car home, I left it for a hour or so, I next went out to try the car again, it was very lumpy on tickover and as soon as you pull off there was terrible diesel knock and heavy black smoke.
up to now Iv checked codes and there is none saved, Iv checked egr valve which is clean, checked the hose from egr to intercooler for splits and that is fine, Iv changed fuel and air filters and it's still just as bad, I'm going to try a leak off test of the injectors tomorrow.
Does anyone have any other ideas that Iv missed?
Thanks in advance
