My engine management light keeps coming on - sometimes for a short while and sometimes for ages...
Plz can some one tell me what the following codes represent that I have been flashing out:
16 & 31
I had my knock sensor changed about a year ago, is it possible that it needs changing again, or should it be ok? If so, where would be the best place to get one from?
Also, I am only over boosting to 1.75/1.8 then dropping to 1.5/1.55 - Is this normal? What should the figures be? One last thing - could this be what is triggering the engine management light to come on?
