B58 tuning and locked DME's
I just bought a new-to-me 2019 x40i, build date 11/2018.
That date is prior to the commonly quoted date of 06/2020 when BMW started locking DMEs - vehicles built after 06/2020 must send their DME out to be bench unlocked prior to being able to flash tune (or use MG flasher at home, apparently a new-ish product in this space ). My question: is the build date of my vehicle enough to be pretty confident that the DME is unlocked? (barring some anomaly like the DME got fried and was replaced some time in the vehicle's life). Is it possible that a dealer service visit in say 2022 could have resulted in a newer DME calibration being flashed and the DME being locked? I have some diagnostic capability with ProTool - can I pull a software revision number or something to confirm that my DME does not require unlocking prior to flash tuning? |

The other type which I will refer to as "hardware" locked is any vehicle made after 06/2020 which is generally understood as 2021+ model year. The HW is actually different in the DME and they fixed the old flaw that was used to bench unlock. This is where the overseas unlock option is required to ship to Femto. They've found a backdoor to allow some limited modifications. It's not really a full unlock like the old DME's. One unlocked by them you can use tuning software like BootMod3. I hope this helps a bit. |

I think this clarifies something that I was confused about.
I was thinking specifically DME calibrations/updates/software versions, and these calibrations would only change with a dealer visit. It seems that the actual condition is that the OTA "vehicle level" software packages will in fact update the DME software version number. |

Download the MHD app, and you can check to see if you need to unlock it

sac02 I have an 19 X5 40i and I had to buy the MHD unlocker to unlock the DME. Not sure where you are located but I’d be down to unlock it for you if your in Connecticut area, highly doubt you are though.

I have a similar age 2019 and it was locked when I checked. I'll see how the mhd unlocker works. I'm hoping I can split the cost a few ways locally. Mailing a DME isn't something I'm interested in doing.
