Finding a charcoal canister (p2422, p0174, p0171)
My car is a 2010 Mercedes Benz C300 Luxury (6 Cylinders 3.0L FI DOHC 183 CID). I don't believe it's a PZEV engine.
So changing the purge vavle and elbows did change something maybe. When it gets really cold outside after putting gas in the car if the car turns on fine then that'll be the real tell.
But this still makes me wonder why the engine light still stays on if this fixed the issue. I need to get behind my computer to upload the pics and video




Im not sure if i cleared the codes when I replaced my purge valve or if I let it fall off on its own. But in my fathers truck I know he cleared the codes after I replaced the purge valve and the check engine light never came back on again.
I do think clamps should be installed, either the originals or even regular hose clamps. The originals snap right back together, I must have removed my purge valve at least 3 times messing around with it and the clamps still seem to work fine.




It also depends which state you're in. Im in MA so get the extended, other states not listed is only 2yrs. I keep forgetting about it since my cars past the mileage now.
The warranty info is in the back of the Service and Warranty Information book included with the Operators manual in the glove box.

The issue had to be the hoses. Those things had cracks. I still haven't put any clamps or anything on them yet either but i'm going to. Need to purchase some and the tool to tighten it up.
I can NOT thank you all enough. Especially you Tim. You are the best!
