| Description of the problem | Hose clamps attaching the high pressure fuel line leading from the firewall-mounted fuel pump to the central fuel rail failed to maintain a tight connection. This leads to fuel leaking past the hose clamp connection into the open engine compartment during cold weather (sub-40 degrees fahrenheit) while the engine is running. When the ambient temperature in the engine compartment rises, either by environment or by heat generated from the engine, the fuel leak subsides. Symptoms when this occurs are a very strong fuel smell in the passenger compartment and also, upon further inspection, observation of liquid fuel pooling on the top side of the engine compartment under tray. Internet research also indicate that this is a fairly widespread problem affecting at least 2015-16 w205 model vehicles, and that multiple mercedes-benz dealerships in the united states have communicated verbally to other customers that this is a "known issue". |
