Well JimF, if anybody can fix electronic parts, it has to be you. My CH92 kicks in and helps to keep the car cool. However, I think it would be better if you could find a way for the fans to stay on a la Volvo until the motor cools down to an acceptable level. My '01 XC's auxiliary fan stays on for about 10 additional minutes after the engine has been shut off. I would think that MB engineers would account for this big V8 engine and the heat generated to accelerate wear and tear on electronic parts (or they probably knew about this built-in obsolescence/fault for repair $$$). I will probably keep resetting the CEL until it gets unbearable.

Oh by the way JimF: if you need to replace the wire harness, it is quite simple until you get to the main connector by the firewall. I found the part ( 129-540-77-05) locally for $462 +tax.
