My M3W 2012 starting problem was nothing to do with the heated seats, but rather a rectifier on its way out! I've now replaced it, but I'm now looking at how I can prevent the new one (£300 - ouch!) going the way of the first. Or was it the second as the one I removed had two earth wires.

I believe the latest M3Ws have the rectifier mounted along the length of the car, i.e. twisted through 90 degrees, but still mounted at the f/o/s (rhd M3W). Is this so?

Has anyone any other suggestions to make regarding protection for this exposed and expensive item?
