However, in any case the system works by a valve controlling the oil flow, either a coil or direct electrical type of valve. It is not a magneto-rheological fluid system nor does it contain permanent magnets. |
If I remember correctly the supplier is ZF-Sachs and the system is called CDC (Continious Damping Control). Here's their description:

And yes, you're right, it works via a valve controlling/limiting the oil flow.

The article I was referring to was saying that the magnetic shocks were going to be suplied by Delphi, and claimed were already in use in the Corvette and Ferrari. I haven't done the research to find out if that is true.

The
"Aftersales Training" PDF says that M3's EDC is based on the E65's EDC system. (p. 101)
