This getting to be a bit of a saga, I had new heating elements fitted after being told that the originals had failed, only to find that I've still got a problem.
i.e. Passenger side still not working at all and the driver's side only seems to be on low heat.
Auto electrician(a/e) has looked at it and with the limited time he had he couldn't find the root of the problem so far. I've managed to find the Z3M Electrical Troubleshooting Manual and sent some pages to the a/e to see what he can make of them. It was a pity I didn't have the information to hand when he was working on the car.
One component that he thought was faulty was a small control unit mounted under the passenger seat P/N 65 77 8 367 242. Turns out that this is a seat occupancy control unit and has been supeceded by P/N 6877 6 940 191. Now when the a/e looked under drivers seat, this component wasn't in place but the connectors where there. Should there be one in place under both seats? Doubt if this part has anything to d with my problem though.
The BMW Real OEM parts catalogue doesn't show this item as far as I can see. I only found the info on it by actually cranking in the P/N.
Be interested to know if anyone else has had trouble with heated seats and what the solution was.
Oh yes, I did get the a/e to check the continuity of the original seat heating elements and you guessed, they are fine!! So it looks like I have a full set of heating elements available!!
