My 2011 C350 has a P0456 EVAP Slow Leak code and had a wet “closing cover” on the right side which I replaced, filled gas tank to check for leaks and now the fuel filter (left side) is wet. Hopefully replacing it will let the code clear after the required drive cycles are completed. Hard to believe there’s no recall yet. Thanks for the video.
Greetings Ali, I am from Turkey and own a 2015 Mercedes with W212 e180 274 engine. There is shaking between 1500 and 2500 rpm at constant speed and when going uphill, there is fluctuation in the rev counter, it may be the filter you changed. Spark plug replacement and many maintenance were done, but shaking and misfiring did not go away. Do you think the problem may be the fuel filter? Regards Thank you
Hi Ivan, I changed the spark plug coil 1 month ago, the service said there was a thermostat malfunction, that might be the reason, I changed that too, I know the thermostat does not cause misfiring, Only fuel pressure pump and fuel tank pump, injectors, crank sensor unchanged
I spent 10 thousand dollars for another vehicle of the same model at the service, the problem still persists, I think there is a simple reason, but I could not find it, what is your comment or opinion on this misfiring problem, best regards
Try to inspect the spark plugs. I had a similar issue on my w164. Kept misfiring. Turned out to be a bent electrode on one of the spark plug. Try checking the coil wires. Have you tried scanning the system with a scanner to see if any codes pop up? You have to use a specialized scanner on these cars that scan the sub systems
Aloha you guys this is the best video great team work
Thank you.

Great vid. Thank you. Do you know what code was caused by this issue?
I didn’t get any codes on this issue, just started to smell like gas…

Hey Ali, have you replaced ignition coils?
