Yes I know all of the pump issues, but before I commit to a very expensive mechanic to look at the pump further, I am looking for the reason the light only comes on after traveling a min of 10klms and then only when I stop at a junction. If I don't have to stop the light stays off. My argument is, if the timing is out, then its out. Why does the car not record it until I stop?
Do you mean slack in the timing belt?
I had a water pump fitted and they said the timing belt was slack and they just tightened it up. Maybe the adjuster might be no good?
