COMPATABILITY NOTICE - BOX CODES & JUNE 2019 FACTORY UPDATE
DME box code and bootloader information must be obtained from the vehicle to determine if a vehicle is flashable in its current state. In some cases we will need to create a file for your vehicle. This process could take several days and multiple dealer visits.
Vehicles previously serviced or updated after June of 2019 may have received a DME bootloader update from BMW. This bootloader version will prevent the Dinan software upgrade from completing. DMEs with the updated bootloader must be removed from the vehicle, and sent to Dinan HQ to have the bootloader backdated. DMEs sent to Dinan for the backdating procedure will not be opened or physically modified in any way. Once the DME is returned to the dealer, they must still be flashed with the Dinan performance software through the OBDII port. If a previously backdated and flashed ECU is updated with the new bootloader, the above process will need to be repeated. Dinan will not pay labor under warranty to remove and reinstall ECUs that were previously backdated, and then updated by BMW or a third party.
