MAC boost solenoid problem, help
What could cause a failure to the MAC solenoid? it's new from 1 month ago
it's not controlling the boost on jb4 all maps same boost as the WG spring? I think the problem from the MAC solenoid power?? what do u think? this code appeared to me for the first time (2DED Power management, standby current control) is it mean the boost solenoid has no power??

the code you got means something is draining your battery. Assuming you have a upgraded turbo running a MAC valve, you probably got rid of the heater element. If that's an open circuit it's most likely running your water pump at 100% when your car goes to sleep. I'd start there. If not you have something else running it down
