There is also a popping noise coming from the exhaust system that occurs when the brake is engaged and the vehicle is idling. …”

“The fuel tank will only fill to 3/4 and the vehicle has an odor of gasoline inside and outside the vehicle when attempting to fill the tank. The vehicle was brought to mercedes benz for service for this issue and they state they do not know how to fix it and having spent approximately $1.000 for mercedes to try and diagnose the problem they advised they don't know how to fix. I have noted a recall for fuel leak probe on mercedes 2003-2008 e class models that has now been closed after mercedes has agreed to fix the issue. …”

“1. Fuel smell coming from car. 2004 mercedes benz c 230 kompressor 2. Fuel sending unit cracked causing the fuel smell. Similar to mb voluntary emissions recall campaign #2008-020001. Fuel smell is constant and could be a safety hazard if passenger lights a cigarette and fumes could combust. If vehicle is involved in an accident the chances of a fire is greater. 3. I had no choice and had to have problem repaired. The replacement part did not fit existing parts which increased the cost of the repair considerably.”

“I have my car in the auto repair shop and the mechanic tells me I need a pvc hose and a oxygen sensor and both those items are on a recall list. He asked me to call the dealer I was told by the dealer that those are recall items but not for my car. My complaint is why if this is a recall item it should be for all cars. Those are the only 2 things wrong with my car. I need help.”
