CEL Help! Wide Open Throttle... Activated Charcoal Canister Malfunction
I have a 2015 GL550 with a CEL P04F000 pop up. Which is Wide Open Throttle... Activated Charcoal Canister Malfunction.
I tried clearing the code, but it’s stored and didn’t clear. I read online that it may also be caused by low engine oil, which I checked and added. Code still there.
Any help would be appreciated!
