Right. Injectors are sorted I think. However the car has now started to play up when starting from cold. I push the button once and it turns over but doesnt fire then I get injection fault and it stops. I then push the button again and this time it turns over then tries to catch then it does fire up but plumes of white smoke come out and it chugs badly. It will then only rev to 2000rpm then I take foot of gas and back on and it will rev normal.
When I pull away it lacks power till it warms up then all is normal.
The check injection light is on constantly, yet when I plug in my reader there are no codes.
Im confused and wondered whether there was any clues on what it could be
1 or more failed glow plugs would be my first guess - white smoke on a diesel is unburnt fuel - you can sometimes smell it in exhaust - but could be other faults
( not to be confused with white steam which indicates a head gasket)
a lot of modern engines supply the glow plugs with power until warm or constantly at reduced power
not like old days of timed supply of xx amount of seconds
Got the starting sorted, was an injector misfiring so changed that all done.
Still have the lack of power. When started, I put my foot down and it goes to 2000rpm then struggles then lots of smoke with a bluish tinge to it. Its like the turbo is not kicking in.
I took the egr valve out and there is oil all around the area and on the valve. Could this be the issue or is the turbo knackered? I have no warning codes relating to turbo
Yes they will work, at first,,, Usually long enough to get the car to a garage...
The codes from the injectors tell the ecu how long to keep them open and closed..
The ecu is using your old codes,, and because the codes are different, your injectors now could be over fuelling or under fuelling.
So if you can imagine them not opening and closing when they should, Then carbon builds up around the valve that sits above the needle, inside the injector. This then stops the injectors closing, this then allows diesel to seep past, drop on the piston crown, wash your bores. Pressure drops in the fuel line, no fuel replaced by air, then from cranking to build pressure back up, this fuel thats laying on the crown of your piston, plus the air,, white smoke..
