Error 120308 - charging pressure control, plausibility pressure too low
Anyone have personal experience hunting this one down on our cars? I'm 535xi pwg
Got a boost leak test/fix based on some suspicious logs before the code ever showed up
The suspicious logs didn't change, so I put on a new boost solenoid and new solenoid-to-wastegate vacuum hose and that's when this code showed up. I put the old solenoid back on (in case the new one is faulty) but still got the code.
Next step in the wild goose chase is to test the wastegate itself. SMH
