BMW E92 M3 problem

I need your assistance and advise, my BMW E92 M3 gives an increased batter discharge error whenever you start the vehicle. But if you switch off the vehicle and on again the error goes away.

I have bought a new battery from BMW and registered the battery but the problem persists.

Any advise will be appreciated...

Could be Voltage Regulator on the alternator or the alternator itself, i had a similar problem where i started the car and everything normal, but when i rev the car all the dash light would go ape shit and the wiper's would go on and the speedo would go balooloos.

On my car everything works okay, just that the radio goes off after 2 minutes when the car is off. I find the error sign irritating whenever you switch on the car and the radio shut off...

Try disconnecting the IBS.

Having a strange problem with mine, changed the battery and the voltage regulator on the alternator.
The car starts fine(not a weak start) but everything resets as if the car was dead. The clock resets, the inside lights go dim.
