Thanks for the pictures and extensive diagnosis. Unbelievable that a "quality" car has such a poor wiring problem.

 

Thank you, especially for the photo documentation. I will add this to the W220 S-Class Encyclopedia at its next update (which I hope to get to soon).

 

no problem I will help out as much as I can. I'm surprised no one else has a report of this problem. I guess when they made my loom some of the wires were tangled together causing a length issue that snapped the wire.

Hi Guys

I too have the same problem. My left light does not work and I narrowed down the problem to the braided section.

Of course the major problem seems to be that the trunk lid is kept from opening too far by the loom. I don't understand why they couldn't use the same mechanism as on the E class.

 

I ended up buying the loom because my connections didn't hold up very well over time. Anyways the loom was priced very well at $177 and comes with the tensioner box and every thing.

My part number was 2208203317 , yours could be different depending on options.

 

Yeah, my part number is the same. However, I live in Australia. Anything relating to cars, let alone Mercedes is a big rip here. It costs $940 from Mercedes. I wasn't going to pay that much for it so I managed to open the textile tape at both ends of the braided loom and stuck a coat hanger thru the loom. Then just ran another wire to replace the one that was broken, cut both ends and soldered the new one in place. Took a bit of playing around with but only cost the price of a new cable, about $5.

The new harness comes with the large plastic housing that spring loads the loom, I pretty much destroyed the old one taking it out so I was happy to see the new harness come with what I destroyed.

 

The wires that feed from my license plate lights have been cut where can i go to have this fixed or is it easier to fix it myself, please help.

 

If they can be reached to cut, they shouldnt be that hard to DIY repair. But if thats is not possible, try a decent stereo installation place. Wiring is their bread and butter.
