changed it, didn't make an ounce of difference.
Strangely thoguh, it will let me kcik in the regen programme again, but because the injector fault rears it's head after a minute it keeps dropping out of the programme.
Got it down to 29% but still got the codes and still in limp mode (yet it will run perfect with the laptop plugged in?!).
Is there any point in keeping on doing this until I get the percentage right down? or am I just causing damage? I don't want to have to fork out £550 for an injector just so I can run the DPF regen when it runs perfectly fine even with the injector error code.
