Foxflash Failed to Read BMW MSD80 DME via OBD Solution

Problem:

Foxflash failed to read a BMW MSD80 DME in E92 335i by OBD. Voltage is 13.6V.

Solution:

Foxflash MSD80 OBD takes long.

For example, BMW 325i e93 took 30 min. Make sure you have a battery stabiliser hooked up. Write when quicker.

Foxflash doesn’t have bench for this ecu.

Remove the ECU out of car, Obd breakout on the bench with pinout and read with OBD protocol. Use godiag breakout box. Do lot of this method.

Or read and write it with foxflash in boot mode.

Flex and KESS3 are great in these on bench mode.
