CODE 4530 Charge Pressure Control Deviation E60 525D M57

[@oualla74]

Hi mate, thnx for the clear explanation. Does your 525d have an electronic turbo actuator or a vacuum controlled one? Does this code also occure with the electronic actuator even though it does not control the turbo by vacuum?

Mines electric and the code returned, so i cleaned the turbo with mr muscle via the downpipe and now no code totally gone and better performance so it may have also been a coked up turbo, video response coming soon.

@@bavarianmotorwerks3353 right. Thnx. Mine is also electric. Wanted to clean the turbo also but I have to inject Mr muscle via the exhaust manifold as I don't have a downpipe. How long did you let Mr muscle sit and did you inject it once or multiple times?

@@oualla74 downpipe basically means the cat pipe or dpf pipe off the turbo and then inject it into the turbo leave it 30mins then drive.
