Might be worth a look around bimmerprofs website for odd misfire scenarios.
Afaik a dud or dodgy mosfet can be intermittent.
Might be worth cracking out the multimeter and checking the mosfet and wiring, and that the ecu is not currently bathing in water.
Also have you considered a compression test...

I was thinking it was a stuck valve or something...might need to do a walnut blast.
No other codes, just Cyl 6 Misfire...
Yeah I did hear about a dodgy MOSFET in the DME, could be a possibility...did also check the white box and it's all dry in there.
Also just did a Compression Test. All between 195-205 psi...which is fantastic in my opinion so that is a relief I suppose!
I did however take out all of the plugs again and smelled them all. Looks like Cyl 4 Injector is leaking slightly as well, since it had some fuel smell on it.
