Create account and buy subscription for PSA DiagBox and a reprogramming token (Google for "PSA servicebox" for link) and do it the official way.
You will need a good J2534 passthru and battery maintainer (power supply).

If I'm not mistaken, 1 token = 1 VIN - this means you can update any other module too if there are updates. But better read terms and conditions, maybe they've changed something.

Well, I gave it a go.
All went well until I tried "downloading", kept getting an error saying it couldn't read from a memory section, or something like that.

It read all the modules and auto detected the vehicle using my genuine Launch Smartlink J2534. But couldn't erase fault codes, so I suspect I will need a different VCI.

Any suggestions?
I have a genuine BMW Icom, Genuine VCP Pro, Genuine CANtiecar multiplexer.

Thanks
