I wanted to turn on my Daytime running light rear lights. I have Bimmercodes and the Veepeak OBDCheck BLE OBD2 Bluetooth Scanner Auto OBD II.

But the "Rear Electronic Module" menu doesn't show up for my 2021 M5C. If I go to the Body Domain Controller menu (I thought maybe that's the one), it says This control unit is not accessible with the used OBD adapter.

I thought they already have DRL's for the rears? I'm pretty sure mine are always on which I really like. Unless maybe they are off when in drive. I watched my wife drive away one day and I believe they were on. It looked awesome.

There is no Rear Electronic Module in G30/F90.
Best way to code BDC3 is to use E-Sys.
