C36 AMG wiring harness


I have recently purchased a 95 C36 and had been blissfully enjoying its superb performance when a mechanic at the dealer told me that my wiring harness is failing. Upon reaching home, I checked the one connected to the thermostat and my eyes almost popped out of their sockets when I saw that the wires inside the fabric sheath were ALMOST BARE! Further prying showed that insulation had failed and crumbles at the slightest motion.

Needless to say I was terror-stricken and my mind was filled with visions of short-circuits, sparks and fried expensive computers!

Can somebody please tell me which harnesses to replace, where they are located so I can check if they are failing, where to get them and the approximate price.

The local dealer wants too much $$$ for it and wont tell me the part number(s) of the harnesses that need to be replaced.

BTW, I just stumbled on this forum. It never showed up in my GOOGLE searches for "C36". This is by far the most comprehensive forum on Benzes I have found yet.

welcome BC36-

you can access tons of info the the wiring harness issue by using the search function

my understanding is that the main engine wiring harness on the M104 can be had via partshop here (cheaper than the dealer) and it supports this site

good luck

AMG parts are $$$$ higher than regular C-class parts!
The engine harness part number is WA-202-540-03-32 & the list is $1,240. !! Takes around 2 to 3 hrs to install.

I would ask the dealer to call MBUSA for "goodwill assistance" on this IF you have less than 100,000 miles!!!

Thank you for the welcome. I have already used the search function re wiring harness and indeed already sent a request for parts from the partshop on this site.

$1,240 for a silly wiring harness!! OMG can't regular C280 wiring harnesses be used for the C36? Is this the one connected to the thermostat housing? Is this the only one that needs to be replaced?

Unfortunately the car is in the Philippines and thus no 'goodwill assistance' is available although the car only has 18,000 kilometers (11k miles) although I dare say that this is obviously a factory defect and should be covered by MB. I am in the electrical field and I have never seen insulation as deteriorated as this. Wonder what compound they used for this, flour maybe?

Thanks for the info MBDoc and Fad. Best regards
