MS42/43 Bootmode without removing from car

Has anyone managed to figure this out yet? I mean winfkp does it, so there has to be a way. I also highly doubt that BMW open these DME's up to write the initial software to them.

Its a real pain pulling these things out to read and write.

Yes, there is a solution for full read and write in the car without the hassle of boot mode.

It just has 2 downsides:

1. its not free

2. its painfully slow (40min for reading!)

That's what I'd do.

They don't. As most OEMs will have the supplier (Siemens) pre-flash the appropriate SW before the units are delivered to BMW.

I used to have the chipster's ms41 flasher couple years ago and that was a great tool.

I bought a momentary switch for that same particular reason, will be drilling the dme in the weekend and solder a wire to run it inside the car. It takes too much time having to pull the thing out, unscrew ground it and so on.
