Put the vehicle in sport mode so you can see the tachometer and rev the engine to 3-4k until you see power flow being sent to the battery. Hold the RPMs at the point where the charging is operational until the desired charge level is achieved.

Can you elaborate on this because the MHT in 2021+ M340i have the starter/alternator decouple from the motor during acceleration to improve emissions and performance...and recouples to charge the battery during braking, deceleration, and coasting. It also occasionally recouples during idle to temporarily charge for a few seconds so that the battery doesn't run down too low.
So this is interesting are you revving the engine in sport mode while driving or in neutral? |
