535i engine noise question..
So I did have a 528 and recently moved to a 535... I was wondering is it normal to hear a humming sound when coming to stop that eventually dies out. I would say its similar to the sound of turning off a vaccum just not AS loud.
Is this normal... perhas the turbos spooling down? |

Almost certainly the electro pneumatic solenoid for wastegate control.
I believe the noise is a failed diaphragm on the pneumatic side |

Question: Turbo Pressure Convertor is not the same as HPFP or is it?!?
Dealer replaced HPFP... said there was a code!!! I'm afraid issue will still be there... I will get the car Monday. I've asked him to drive it and check for noise once they put in new pump. |
