Airmatic Shuttering?

Just bought a 2005 E500 with the airmatic feature. When I start the car and put the trans in reverse, I can feel some sort of shuttering in the brake pedal, does anyone know if its just the airmatic adjusting? It does it sometimes when I have my foot on the brake at a stoplight as well.

Sounds like the AirMAtic or SBC brakes charging.

It is the SBC charging and doing a self check. Nothing to worry about.

The SBC is a busy little rascal, frequently recharging or doing something that feels like a vibration through the brake pedal, as well as emitting buzzing-type noises. I wouldn't call the vibration a shuddering, but we're probably talking about the same thing - and so something normal.

I was just going to start a similar thread on this. I guess it might be just the SBC but I feel the same thing and I assumed it was the airmatic as well.

It's the SBC that you're feeling. Another weird characteristic of the SBC is the pump operating when your car is parked. Mine usually goes on whenever I open any of my doors.

So that's the SBC making all that noise? I was thinking it was the airmatic leveling out the car. Anyone know where I can read up on the SBC feature?

Thanks.

The SBC STOP feature seems like it would have been useful for me in all the traffic I drive in. Too bad it was deleted in MY05.

Morning Samoan,
This calls for another of my good news, bad news themes.

The good news is SBC Stop was NOT deleted in MY05.

The bad news is that it has never been included on US imported 211's.

Sorry for my sense of humour, but I have just got up,

Morning everyone,
John

Damnit John, you should have given me the bad news first because after reading the good news portion of your post I got so excited I stopped reading and went straight to my car to try it out. Only to be disappointed.
