2011 MCS All4 2C90, 2C91

Mini Countryman.. Still somewhat new to me, had it about 4 months.

It has had a plethora of codes over the time I've had it. the only ones remaining are these. 2C90, 2C91.

When I began looking into these I contacted original owner who told me that the turbo, HPFP, and Vacuum pumps had all been replaced at the end of his extended warranty period.. The bypass valve is a new Forge unit and seems to function properly.

Haven't checked for boost leaks yet..

Haven't had chance to check the wastegate functionality.

The boost pressure thru the OBD port read on the bluelink app is ~9psi.

Anyone encounter something similar?

for anyone following this the issue ended up being a sticking FORGE bypass valve.. I replaced it with a stock valve and the issue has yet to reoccur.
