W220 AC Compressor

[mr. shr]

Hi All,
When I press the EC button (light on) the compressor does not stop spinning.

On my past W208 and on my current W202, pressing the EC button causes the compressor to stop turning. (You can physically see the rotation stop and start each time the button is pressed).

Does anyone know if it's a different system on a W220? I'm concerned there may be a fault with my compressor if it doesn't stop when the air con if off.

Thanks for any help/input.

Thanks Malcolm,
My car is a year 2000 so not really one of the later cars.
Do you know if it supposed to stop turning on cars of that age?
