    Cars with the latest BMW software require a bench unlock to flash over OBD.
    Cars Produced after 06/2020 can only be tuned with a special unlock by FEMTO, due to a new tuning protection. This means your DME must be sent to FEMTO in Finland. After your DME is unlocked by FEMTO, MHD will automatically detect the FEMTO unlock.

    Flashing back to stock will always fully remove the unlock and the DME must be unlocked again for flashing MHD.
