That type of cable will do basic coding with NCSexpert for example, but not FLASHING (winkfp or mss6x flasher).

You will brick it.

You need one of those cables, but one that's had ediabas firmware loaded on.

I bought from

in regards to the "Switch," I believe that's needed for E46 (mss54) to get into the engine module versus something like airbags or light module. But msss54 doesn't need the cable flashed with ediabas like mss6x does, so it's kind of weird that these companies pick a cable with a swtich for their e9x offerings. I guess it's nice for people like me, who have both e9x and e46 - 1 cable for both cars.
