I have a complete CMGS kit for sale off of my 135i. It is this one listed here:

The solenoid is bad in it, so that will need to be replaced to the tune of about $40. Other than that, the kit works like it is supposed to. As you can see, retail is $659, but the kit isn't brand new and I'm sick and tired of dealing with it after my BMW is long gone.
Comes with a CM7 and a CM10 and all tubing, tank, pump, controller, wires, and other hardware.
My loss is your gain, $250 shipped.
Pics will be posted in a day or so.
