Check engine and tmps
I have a 2009 ml350 (bought recently) I have a check engine light P0455 tried a new gas cap cleared the code and it came back. Any insight on what this could be and where I should start to look?
also the tire pressure light turns on. When I start the car it flashes for about a minute and then stays lit. I tried resetting it through the cluster but that doesn’t clear it. (My tire pressure is correct) btw am I suppose to see the actual tire pressure for each tire on the car cause I don’t see them.

Code P0455 is a severe leak somewhere in the evaporative system. Please read the PDF and note that the leak could be anywhere including the Fuel Tank Pressure Sensor which is located in two positions depending on year .
You must find a mechanic who has a Smoke Machine to locate the leak.
