Electrical fault????

Post by drago3108 » 05 Jun 2017, 12:15

I have a 318i, 2002 automatic, e46 model with a n46 engine.. The car cut out and wouldn't restart although does turn over, the temperature gauge was all the way to the right showing overheating but the engine was still cold.. got it home and left it to the next day but still the same showing overheating and will not start (it happened two weeks ago as well and was' put right' by disconnecting the battery and touching the neg and live leads together to reset the ecu but this time doing the same has not cured the problem).. I have changed the engine coolant temperature sensor and the radiator outlet thermostatic switch and I have reset the ecu but still no difference... Any ideas please?:confused

Other than extremes, the coolant temperature alone won't affect starting.

It reads like you have an electrical issue if it won't turn over at all.

If it's an auto dose it need to be in park to start as the old auto cars some time you had to mess around with the gear selector to get the engine to start prob not the case hear but worth a go
