Hi,
Car :
R60 Cooper s all4 AutomaticFresh ******* chain since 6k km
Fresh oil
New boost pressure sensor
new plugs

Conditions when error is reproducable:
cold engine then driving for 3 -5minutes, acceleration and the throttle release and cruising and slightly slowing down with no throttle. Never ever under load and never ever when engine totally worm.

​​​​​​Error:
2c58
Limp mode
When this occcures it is always combined with a559 error.

History:
First time I've ever had similar issue I had intake solenoid error together with this but since then never and I've reproduced 2c58 already 10 times.

What do to what to check?
What to monitor via OBD.?
I'm trying not to get log file with intake pressures during error ocures but no success till now.

Tried to charge battery but this has not eliminated the error but I have some doubts if it's not related to some electrical issues.
i have quite high charging voltage and discharged battery when left car 10 minutes on lights.
