I found this part is making noise in my C240 but I do not know what is it. Can somebody tell me what is it and is it normal or need to change ?

That is the purge valve (regeneration valve in Benz speak) It clicks loudly with age & has seen 3 redesigns.

P/N A 000 470 35 93 is the latest I have. Don't be confused the 45 93 preceded it.

It's part of the EECS (Evaporative emissions control system) If the noise worries you then replace it or mount it on a rubber pad like later models. It's not a major issue but can be annoying.

BTW - I note that the US is not using a W203 specific part number because it's common across a number of models. They do these things to confuse the hell out of us customers.

I notice you guys have a c240 with a v6 engine.

So just wondering, does a c230 have this as well? If so, where is it located at?
