Hi everybody,
I need your help
I am getting a reduced power error on my M5 and the car shakes like hell

and when I took it to the stealer they got these errors

VANOS oil pressure - No pressure;
VANOS control, intake bank 1 - Actual value too high;
VANOS control, exhaust bank 1 - Actual value too low;
VANOS control, intake bank 2 - Actual value too low;
VANOS control, exhaust bank 2 - Actual value too low.

and all cylinders are misfiring with cutoff
and they think that they need to replace both VANOS's AT adjustment



could you please help me with issue if you have any idea?

I think those stealers do not know anything about these care
