[Mihkel440i]

Hi, i have a problem with my 440i 2016. The car is cutting at high rmp when wot. I have not felt this before the car runs mhd stg2+ and xhp stg3 for one year now. Yesterday when i first time felt it i read the codes and i got codes from vanos. I erased them and they have not came back but the issue is still there. I will add here picture of fault codes and the 4th gear log. Where should i search the fault? Rail pressure seems to do some odd drops.

213601 - Battery drain from what I’ve been reading might be good first to see how many volts it’s producing

130715 - vanos actuator probably needs replacing then reset adaption values, I believe these sit at the rear of the engine

No need to reset adaptations with vanos replacement on the b48/58.
These are pretty easy to swap. The specialty spanner helps, but isn’t required. There’s plenty on the forums about how to replace these.
