Anyone on a M340i or G20 have top expert mode tips to share?

In particular I'm looking for
- actually turn on AC when engine off (vs aux fan)
- make the car use hybrid battery for air cond when engine off
- enable exhaust valve option in idrive in 2021 M340i
- enable RPM bar in HUD in M Cluster
- replace ALPINA word with M in Alpina cluster
- enable burbles pops bangs in 2021 M340i
- ask iDrive to stay on longer (play music) when engine has been shut down
- get AC to stay on when engine has been shut down

Answer: I'm pretty sure the A/C is belt driven and not electric, so not possible
- make the car use hybrid battery for air cond when engine off
Answer: I think I see evidence in my car that, as long as there is a certain charge in the MHEV battery, this is where all electrical power is coming from both with engine ON and engine OFF (and driving the cabin fan, that is ..)
- enable exhaust valve option in idrive in 2021 M340i
Answer: I have it (Engine Sound menu) from factory in my M440i and if you search there are posts here how to enable it with BimmerCode,
- get AC to stay on when engine has been shut down
Answer: See above, only fan is electric and can run (max 30 min).

it's in the bimmercode cheat sheet thread page 2 or 3 i think.

i've coded it but haven't tried it. don't want to disturb the neighbours.

Mild hibrids no way for burbles (even if can lol not bimmercode haha)
no rpm bar without M track module on S18a

I'm pretty sure you can just turn the iDrive back on by just clicking the volume/power button.

"replace ALPINA word with M in Alpina cluster"

Anyone know if this is possible/what the code is?
