My foxflash tool cannot read and write BMW MEV946 protocol by OBD, any advice?
Make sure you have done driver seatbeal on, hazzard lights on and driver door open so dash not got in sleep mode.
If still failed to read/write via OBD, there is no VR file on server.
Also try to read ecu via OBD on bench using godiag breakout box.
Or use kess v2. Kess make it via OBD without problem.
