Hello,
I have a problem with this thing. The main problem is that I can't find this part in autoparts shop to order it. Please, help - I need name or part number or any info !
The car is 2006 W203 C350 4MATIC (M272).

 

So this is a strange one. I was looking here and it shows the PN as 20358304196. However, the PN doesn't look right, as the number of digits is wrong. Also I can't seem to find a photo of it. I'm thinking there's a typo in their parts database.

FCP lists the part as 203-830-39-96. However, other sites show a different looking part for the same PN.

I'd call the dealer with the 2 PNs mentioned and verify the correct PN. Then you can order from your supplier of choice. A lot of 3rd party sites get the occasional PN wrong, so you must verify with the dealer. Also the "part" might include both the plastic lid thing and attached hose.

For plastic pipes, I recommend the dealership or OEM only. Not all plastics are the same, and I have seen plenty of aftermarket parts use incorrect or inferior materials before. The last thing you want is a coolant system failure on the road. Also many plastic parts are poorly made, which means you may have fitment problems or other defects such as broken bits from the manufacturing process.

Just curious, how did you break that off? There's a similar looking part for my car, so now I'm wondering if mine is starting to go as well.

Lastly, there should be a PN stamped on the part somewhere (MB is generally quite good at this). It might be on the hose attached to where the plastic pipe broke off. Can you check and post a photo?

 

Thank you for your answer.
I also found this part you found. But this is the back side of the part - which is ok. The broken part is the other, and it is NOT on the pic, so maybe it is a different part, which I can not find...

It just broke by itself while I was driving... No idea how and why. Good thing it happened 1km away from my home, so I got home successfully.

 

Can you please send a pic of this part on your car.

 

The equilvalent part on my car shows a different PN, but if it's the same part I'm thinking of, it looks very similar. I don't have a photo at the moment unfortunately. Also I've never removed the part from my car, so don't really know exactly what it looks like.

 

I think I found it.

That's the one. As mentioned before though, verify the PN with the dealer. MB is notorious for often having multiple versions of the same part (in which case you want the latest), as well as similar looking but non interchangeable parts. Seen this many times over the years, including stuff like pipes and hoses.
