Any one have a c43 engine harness? Part number "2085402805" or an alternative? According to MB parts list it seems to fit clk430 and clk55 models, but on the clk harness parts list non of which has c43 as capable. Keep in mine 2.0 and 2.8.

Thanks.

 

I have 208-540-2332 from my 55 swap. Donor car was a CLK55. Not sure if compatible with the ME 2.0 or not - I kept the 43 harness when I swapped.

 

I also did a swap. From a CL55 NA. The 2332 wouldn't work as i told, maybe due to O2 sensor connectors.

 

Do you not have the harness at all? Im aure any harness from 98-2002 m113 will work no?

I had a 2002 ml55 motor in my c43 and stock harness was used

 

the car is up and running for a month, but before the swap i used to get cam signal code even with new sensors. It causes the car to have a hard start and on a good start the engine light may go away. Car will start right up about 7 out of 10 tries. Part of swapping it was knocking two birds with one stone, since the code could also be off timing. Motor has been around.

*When it starts the engine runs strong and normal, ecu does its normal cycles of regulating things (fan, secondary air, egr etc).

 

The Dealer told me the part number for the C43 harness is 202-440-0010, and it's no longer available.

Where are you getting "2085402805" from?

 

@x463 , does your W202 have the 208-540-2332 harness installed or the original C43 harness (202-440-0010)?

 

the "2085402805" Is labed on the cars harness. If you search it it'll show c43 clk55 clk430. If you searches the "2332" it doesn't show the c43 as a compatible car, ranging from 1997-2003

 

Your original post had "2085402805", not "2025402805." Was that a typo?

 

Yes 208* to be correct. I was reading your responce with a 202 part number.

 

Interesting. What year is your C43?

 

98. two tone interior, Cellphone, Gated 1-4

 

@Killahbee we have the same problem. I need a replacement C43 engine harness too.

I purchased a 208-540-2332 wiring harness from a 2002 CLK430 on eBay and haven't installed it yet.

I'm keeping my fingers crossed that @x463 can confirm that that works on W202 ME2.0 ECU's as they are readily available.

 

I asked "zayed" if "2332" will work, he told me it def wont. You were the one that probly snatched it off my watch list on ebay. From what i understand, it'll connect to your k40 and ecu, it would also work with ac and alt since clk, c, e of that era use the same stuff. But when i look at the diagram i belieave the o2 sensor is what's different.

Thats harness you got is for clk430. If you try to purchase a clk430 o2 sensor it wouldn't fit a c43.

If you get far in installing it maybe the sensor connector is what's differen't.

 

I'll have to check next week. It's the original 1998 C43 harness I'm running.

 

I "snatched" this one off of eBay as well: https://www.ebay.com/itm/235221601501

I found a Mercedes Wiring Harness Repair Specialist online named Victor. Here is his website: RestoreYourMercedes.com

I emailed him and he said that he can rewire the original C43 engine wiring harness if it is shipped to him, but he did advise that its a "very long and expensive process."

Once I receive the eBay wiring harness I'll compare it to the CLK430 harness and will verify Zayed's findings. I'm pretty sure he's right.

@Killahbee , the same seller I bought the C43 harness from just listed another one on eBay. Part number 208 540 28 05.

It's in better condition than the one I purchased from him earlier this week.

If you don't purchase it then I might buy it as a spare.

Also, I spoke with Victor from RestoreYourMercedes.com. He said the harnesses from late 96+ onward are much more reliable than the pre 96 harnesses.

Victor said they're made of Teflon and rarely, if ever, fail.

He thinks my misfire issue is likely caused by another problem.

Harness is 208-540-2805. This is the original harness to the car (bought car from original owner - have all records).

 

He's selling it for what you can buy it for brand new from the dealership. Plus how do you know if it's the harness without running a continuity test between both ends of the harness? The Cam position issue is related to open circuit, which can be damaged harness or damaged ECU.

If the continuity between both ends of the harness is fine a ecu change is probably cheaper.

I think it's the ecu. Start your car and when you get it started kneel down near the exhaust for 30 seconds and see if you hear a hickup in the idle.

 

update* I asked MercedesSwapShop, it's most likely a harness issue, but a clk430 wont work even though it'll plug into the ecu and k40. The reason being is 01-02 clk430 has two CAN wires which control the TB with a m.e 2.8 ecu.
