I bought this m235i xdrive a few months ago and put downpipe, intake, charge pipe and intercooler in her. She is ready to be tuned. I chose mhd tuning for my tuner. Went to flash the car and it took 30 minutes to connect and when the app said it was flashing the ECU a "Unable to erase memory" showed right under it and there was no further progression on the app. I took it out to see what is wrong. Went to bed thinking everything was fine. Woke up to 4 codes and the car wont attempt to crank, or ever turn over. Someone on this website had a similar problem and need to purchase a obd2 hard connection vs the bluetooth connect, i bough one it is arriving tomorrow. Just seeing if anyone else has had problems with MHD tuning. Please let me know!

I would definitely recommend a 12V battery charger, especially for the first time flashing.

I had it hooked up! Battery is reading full charge too!

Ah okay I thought it was a battery issue.

I have only used a wired connection to flash and haven’t had any issues but I have seen people say their flash failed with the Bluetooth adapter and then worked with the wired one. Hopefully that’s your fix
