DME is toast even after fixing the MOSFETs. Still no good.

Car is paper weight now

After searching I can't find everything I need to fix this myself I don't have the money to have BMW fix it.

I see I need the DME and the key slot.

Anything else I need? Can someone take mercy on me and give me run down of what I need when buying a used DME and Installing it.

Not sure if a used DME will work. You will need the "keycoder" program for this. Linky

Alternately you could use these guys, but not sure how much they charge.

And here's a rundown of how things work. You can start from page1 to let the whole thing sink in, or you could jump staright to post #29.

I don't think you need a key slot.

Hope this helps a little, and maybe points you in the right direction.

GL and keep us posted. This is an interesting topic - no pun intended.

Thanks for your input.

It's a bit disoreintig trying to sift through all this info.

Wind really was blown outta my sails when the mosfet fix didn't work.

Amazing how a perfectly running car is made junk by the damn dme.

Either way I'll update as needed and when I find a fix
