It's a big black box that is about 4 inch x 4 inch by 1/2 and sits on the firewall on a w126.

There are a number of posts on how it can be repaired. Often some of the solder joints fail, and can be renewed by heating with a soldering iron. Especially vulnerable are the large joints at the main plugs. A couple of mine had failed. Today I pick up my new idle control valve, which will, hopefully, mark the end of my car's idle problems!Ned

after changing the unit it cured my idle problem so decided to pull the old one apart,i found a few hot spots on the circuit board which apears to be a failed diode and some sort fet,transistor or something.
