1996 C220 Engine Wiring Harness

It appears that my engine wiring harness is starting to age and malfunction. This is causing repeat check engine lights to occur, but my car still runs ok. The dealer wants $1080.00 for the part (Part #:A 202 440 96 05), and I was curious if this can be purchased anywhere else for cheaper. Has anyone found a place other than the dealership that sells this?

Did some research on that, there was one on e-bay but it was for a 95 model not a 96'. I would keep checking the ebay site for one popping up.
Here is a link to some history of several years of problems with that particular models wiring harness issues that you most likely know about.

Those harnesses do not look like they are even worth trying to fix after reading above article. I would hate to even ask what the labor charge at the dealership would be to install a new harness. B

I replaced my C36 (M104 engine) engine harness by myself. It is quite straightforward and took about 3 hours. Having said that, some parts were a bit fiddley for access (eg. anti-knock sensor and starter motor). I would think MB or a Merc experienced auto-electrician should charge no more than 1.5 to 2 hours labour.

This link is very helpful:

BTW guys... I rebuild these harnesses myself, all soldered and shrink wrapped, using fuel and heat resistant AUTOMOTIVE wiring, along with loom and tape. I just got done with another c280 harness, so I am open as of now... I charge 300.00 + shipping, + any new "pin bushings" (electrical connestors) that i have to order from mercedes. . the Last c220 harness was a total of about 336.00 after all was said and done.

Pretty cool. Do you require the harness to be sent to you leaving the car down or do you have spares that can be used and a core charge to send our old ones back to you?

I would have a hard time having my car down that long. As you can guess, I know I have an issue but it isn't REALLY bad ie the car still runs fine.

As of now, I need the harness from your car to rebuild.... HOWEVER.. If anyone goes and has a NEW harness put in, they could send me their old one as a "donation" - this would allow me to ba able to do an exchange, and limit down time! --Just a thought...

Also, as with EVERYTHING it seems, the cost of supplies is going up, nothing insane, but here is where i am sitting right now:

(All prices are not including parts such as pin bushings, ETC)

c220 harness - 380.00
c230 harness - 420.00
c280 harness - 460.00
c36 harness - 480.00

Other harnesses such as E-class harnesses are estimated to be in the range of 350-500.00 for full rebuilds. Price also varies , depending on how badly degraded your harness already is! I have had 2 harnesses so far that were nothing but dust and copper once i unwrapped the tape!


Keep in mind also... I am not just wrapping your wires in tape, I am REPLACING EVERY WIRE! I also use solder and heat shrink tubing on all connections, and replace any broken plugs.

My harnesses are then sealed and wrapped with 3M 33+ tape.

For an extra 30.00 I will do a bit of "overkill" -- After the first time the harness is taped, I will cover the harness with wire loom, and tape it again, making it even more protected, not to mention better to look at!



EDIT - THIS POST IS OVER A YEAR OLD. PRICING HAS INCREASED DUE TO INCREASES IN PRICES OF SUPPLIES AND SHIPPING.

Hi doin12volt,

My repaired harness arrived a few days ago, many thanks!

It looks far better than new and certainly more robust to withstand the engine bay temperatures. A very professional job indeed. Now I just need a spare few hours to install it...can't wait!

I have a question. If I send my harness out, how would you suggest I ensure that the I know where to plug/connect them back after I get the repaired harness? thanks

C220 1996

Are you still doing wiring harnesses. What would it cost to do a 1996 C220? And where are you located? Thanks.
