Hi,
I have a 2011 Countryman S All4 with 80k miles that has been unreliable recently.
It has had a brand new turbo and wastegate, turbo pressure regulator, turbo diverter valve, exhaust cam sensor, spark plugs and trans service. Since then, it did about 500 miles without issue, then suddenly dropped into limp home mode and Check Engine light on.

I pulled the followed fault codes:

2DD0 Valvetronic System: Control Deviation Warning Threshold exceeded
2DCE Valvetronic System: No Adjustment Possible
2C57 Charging Pressure Control, Plausibility Pressure too low
2CB3 Wastegate valve, Activation: Suspicion of fault in Wastegate Activation

I have googled all of these with no conclusion. Does anyone have any ideas which troubleshooting steps to take?
