Hi Guys,

Recently i have noticed a loss of power on my 320d, i've scanned it and 2 codes have come up.

-44cc
-4530

has anyone had these codes and managed to resolve the problem ?

Thanks again

Quick google gives you these

44CC (charge air pressure actuator)
4530 (charge air pressure control, small turbo control deviation)

Looks like your turbo actuator has failed, I think it's roughly like an electronic boost valve, so it's basically not letting the turbo build boost to create power.

You'll need to research in to it/contact an independent but from my quick google it's a control unit that needs to be replaced, and isn't anything to do with the Turbo unit itself, but I could be wrong.
