Source for CIS-E Control Unit
 

It looks like I may need the CIS-E control unit for my 1986 560SL.
Does anyone know of a good source? Is their some place that can test the unit?

Many Thanks

I just had to replace mine.

The service CD's outline a process to test if it is faulty. If you get confused just shoot me an email.


I ended up just buying a used one, after posting a WTB in a couple MB forums. The unit new was $1700-2000 depending on where i looked, but I got a working used one for $165. (this is for a w124)

EDIT: See if you can find one at a junkyard, and ask the guy if you can try it out before you buy it. I can change mine in 30 seconds with a 10mm socket, but again I don't know where yours is located.


Good Luck.
