Mercedes Fuel Tank Cap - Genuine Mercedes 2154700105

Product description

**A common source of EVAP fault codes** If your Mercedes has a check engine light from EVAP related codes there's a good chance that the fuel tank cap needs replacing. A faulty fuel tank cap that does not hold pressure in the fuel tank will allow fuel vapor to escape into the atmosphere as well as prevent the fuel system from pressurizing properly. If your gas cap has gone missing we also recommend replacement as soon as possible. Not only will you have a check engine light due to an EVAP leak but a missing gas cap also allows for dirt and other contaminants from getting into the fuel tank. This Genuine replacement will fit and function just like your original.
