Codes 003100 and 002A82

2011 Z4 35i ... No CEL ... after driving sometime, CEL turns on saying loss of power. Carly shows 003100 (boost pressure control, shutdown) and 002A82 (inlet vanos). Didn't notice any loss of power though. After clearing codes, turning off and turning on CEL disappears and comes again after sometime. Replaced Vanos solenoids, camshaft position sensors and boost solenoids. Checked fuel injectors. All are good. Didn't notice any leaks. Replaced oil filter cap also.
Planning to drop off at dealership next week for annual oil change. But wanted to give another shot. Appreciate any suggestions.
