Roxxor. I liked your DIY and I understand you could not cover all the details.
Guys I know this is an old thread but help me out if you can.

My 2014 F10 came from factory with Blind spot (HC2/SWW) installed. A few months ago it started acting up until it finally died. ISTA-d shows SWW in Red (ECU not responding).

I picked up a master and a slave HC2 from a 2017 F10 (attached pics) and have a few questions (search did not answer these).

1. Could I get lucky by plugging in the used HC2 and they work
2. If not what do I need to do on a macro level to make them work. I have Esys and have done coding but not flashing - doing a Search gave me some guides on what to do on flashing.
3. Would I need to get the HC2 software to be compatible with my car by flashing
4. Would I need to also code it in some way to match specific values to my car like VIN etc..
5. I imagine this would be the same process for most ECUs whether new or used?

Again I am not looking for details just an overall sequence of what I would need to do.

Thanks.
