9 times out of ten it will be the sender/senser that is faulty i've gone through a couple now they seem to wear out quite quick and you've only got to overfill the oil a tad to knacker them the senser is next to where you put the oil in. if you disconect the wires and look down the hole you might well even see oil in there if so it's dead. but even if you dont it would be the first thing to replace |
