Three problems related to other fuel system tank filling/charging have been reported for the 2011 Mercedes Benz C300. The most recently reported issues are listed below.
Car interior smells of fuel after filling up the tank. The smell is also noticeable when parked in the garage. My mercedes e350 also had the same issue and it was determined that it was a defective fuel cell sending unit.
Car will smell like fuel after filling up on full tank. I took the car into mercedes of greenway in downtown houston. They discovered a leak in fuel system, it's causing the check engine light to come on because of the inadequate pressure. When I had the car parked in my garage, my whole house smelled like fuel ! it's a big safety issue/fire hazard. I've seen other 2011 C300 are experiencing same issues.
Takata recall had vehicle checked after consistent smell of fuel upon filling up the car. Mechanic discovered the fuel filler neck to be faulty because of plastic connector fuel tank.
