Fuel leak when tank is full w204
Hi all, I have a Mercedes c300 (2010) and the last month or so, whenever I fill up the tank the gas tank leaks fuel. When the tank is full and I park my car, there is a definite puddle from small drips of the gas tank. I realized this since the odor goes away after after the tank is only 3/4 full. I've also experimented filling only 3/4 full and no leak nor odor.
Around that same time when the fuel leak started, I got my oil changed at a 3rd party MB specialist and I believe think they put too much oil from the dip stick, but the "check oil level" message went away now after a month. Could this fuel leak be related to the higher than normal oil level?

I was reading up on that and I believe they may have included the C-class for fuel tank under unlimited mileage for my year. I'll take it to the dealer and see what they have to say.
