I smelled fuel in my garage occasionally for the past 4 months. I assumed in was the gas heater but when I park my car in others garage I smelled fuel. A friend suggested it might be my car. I took my car into service for my 50K service and asked if they could look into. Mercedes Benz informed me it is wet around the fuel hose connector. Before I only smelled it twice a month in the garage. After one I got it back from service, I smelled fuel inside the car while I'm driving.

At cold start, especially when the heater is on, the cabin smells of raw gasoline. The issue is quite annoying and extremely dangerous. After performing a google search about the problem, I've noticed that others who own W205 have experienced this problem. This is just one example others' complaints: M.carcomplaints.com/Mercedes-Benz/metris/2016/fuel_system/fuel_propulsion_system.shtml
