Also, after deciding my car I was able to find out it's a B46d and not B48 so hopefully i don't run into issues bc of tht either. Super confused rn lol

It’s both the production date and the ECU software date. If your car is produced in 2018 and it was flashed with the updated ECU software from late 2019, you lose the ability to flash BM3. So the criteria for being able to flash BM3 is limited to
1) Your car MUST be produced before March 2019 (Or so the guy said on another thread on M2C forum about cars produced after March 2019 cannot be flashed with BM3)
2) Your car MUST have the early 2019 ECU software |
I know my car was produced in December 2018 but I have no idea when my ECU was updated. How would I check?
