Hi
Have a bmw e60 530ia 2006 02, sometimes vibrates car idling you can feel it in the seat, the steering wheel when I turn off the fan works raised idling and the car is working fine with no vibrations, as soon as I put on fläckten begins vibration feels like I'm sitting in a boat.

Have replaced solenoid valves, spark plugs original bmw bosch, air filters, ignition coils, updated the software in the car, air flow sensor,

nothing has helped, it may be that my AC compressor is working hard?
there are two kinds air flow sensor to precisely n52 one is 13627547822 I have
the other is 13627520519 does anyone know what the difference is?

vibrations make me crazy
