2017 e300 4matic
P04F0 Code
Hello! Seeing if anyone has had a similar problem. I have a 2017 E300 4matic 2.0 (274.920) I have a P04F0-00 ( Wide Open Throttle Regeneration Of The Activated Charcoel Canister Has A Malfunction)
I replaced the crankcase ventilation assembly which includes the wide open throttle line but I have the same code coming back. Also tried smoke testing and has no leaks. Have taken to the dealer and said I needed a purge line but still no luck.
