Hi All,

I have a problem with my door control module and it seems to be a common fault with these cars. I was wondering if anyone knows if the unit i've found 2nd hand will work.

My part Number: 209 820 22 26
2nd hand unit: 209 820 12 26

The chap said it was off the older non face lifted CLK W209. I've tried to get my part fixed with no luck.

Thanks in advance.

 

The only part numbers I see listed are 209 820 22 26 (right door) and 209 820 21 26 (left door).

 

Hi,

I think the other part number is from the non face lifted model. Ill attach the ebay link. The part looks exactly the same. Thanks for your help.

I don't see that part number listed in EPC, and also it does not pull up anything on parts.com. Here's the list of parts from EPC:

Is there any chance you can get the parts list up for the older CLK W209? How can i show pics on here because its definitely the part number 209 820 12 26.

 

Here are the two control modules.

2nd hand module on ebay.

 

That parts list came from a MY2003 W209 CLK320, so there is no older W209. I do know that sometimes the part number printed on the part itself is not a "real" part number. This may be the case. I don't see that the seller makes any warranties, but maybe if it doesn't work he'd take it back? Considering the price, it seems to be worth it - this is a US$500 part new.

 

I just paid $700 for this repair including install.

 

Sounds about right - $500 for the part, $200 for labor (at dealer rates). In the USA, you can get the part for just north of $300 at parts.com, and it's an easy DIY if you are skilled in removing door panels.

 

I've got the part off but think i might give that other part a try. Do you know if the new parts had to be programmed to the car?

 

No coding is needed.
