Yes, you've cracked the case - let me explain a little further.

I've had 2 VCMs that I've read from the ECU - one before a local "BMW coder" tried to code in 3AG (backup camera) that I've tried to retrofit (it connects to the BDC module). It didn't work and he supposedly coded everything back - however when I read the ECU afterwards, there was this CAFD in BDC.

Before: CAFD_00001DF7_006_024_071
After: CAFD_00001DF7_006_024_144

And that's why ISTA+ complains about BDC... How can I put BDC back to the right state, i.e. downgrade the particular CAFD?

PS: How the hell do you know such details about particular CAFDs? You blew my mind away!

Last and foremost, thank you very much for your help!
