Hi there,
Maybe someone here can help me in understanding how often it is normal to hear the air pump on a W212 Estate.
In the past I don't remember even hearing it but after the last service 29k miles, I don't know why but I hear the pump. I hear it sometimes in the morning and then sometime again during the day.
I'm not loading the car as if doing that I would understand the pump adjusting the ride height.
It goes for about 5 seconds or so.
I leave the car parked during the night on a slight inclined drive and during the day at work it sits perfectly horizontal.
Maybe it's just me (hearing got better?LOL)
I must say that I can only hear it if the radio is OFF and have no one in the car making any noises.
Engine is a E350 CDi
