3.0tdi injector issue?

[slice636]

I'm having a slight misfire in cold mornings and it also feels like I'm down on power slightly especially mid range,
I've fault scanned it with no errors showing but these are the injector figures:

Cylinder 1 injection quantity variation 0.39
Cylinder 2 injection quantity variation -0.16
Cylinder 3 injection quantity variation 0.15
Cylinder 4 injection quantity variation -0.78
Cylinder 5 injection quantity variation 0.39
Cylinder 6 injection quantity variation 0.02

Any help is appreciated!!


Cheers

Hi, these values cannot tell you 100% if injector is bad, but can tell you what ecu is doing. All these values should be close to zero and at same values. So in your case 1,4,5 are out of spec, but it maybe should not cause problem what you have. What else have you checked before pointing to injectors?

Hi, Sorry for the delay!
The problem is now resolved and it was down to a faulty egr valve, which was easily blanked and mapped out :D So no more smoke and feels more responsive
