Fuel/propulsion system, Mar 19, 2020
THERE IS A VERY STRONG GAS SMELL WHEN THE HEAT AND/OR DEFROSTER IS TURNED ON. THE HIGHER THE HEAT IS TURNED UP'THE HIGHER THE GAS SMELLS. THE SMELL LINGERS WHEN THE CAR IS NOT RUNNING/CUT-OFF. I HAVE NOTICED THAT THE STRONG SMELL OF GAS DOES NOT OCCUR WHEN THE AIR IS TURNED ON'IT ONLY SMELLS WHEN THE HEAT IS TURNED ON. IT IS SO STRONG'IT WOULD LITERALLY KNOCK YOU OUT.

Fuel/propulsion system, Dec 18, 2019
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".

IN FEBRUARY 2019 THE C300 ENGINE LIGHT CAME ON, TOOK THE VEHICLE TO THE DEALER AND THEY SAID IT WAS A BAD CATALYTIC CONVERTOR, AND THE DEALER TOOK THREE DAYS TO REPAIR IT. THREE WEEKS LATER IN MARCH 2019, WHILE DRIVING 25 MILES PER HOUR STRAIGHT ON A RESIDENTIAL STREET THE CAR SHUT OFF WITHOUT A SOUND, ALL THE LIGHTS ON THE INSTRUMENT CLUSTER LIT UP, AND THE CAR COASTED TO A STOP ON THE SIDE OF THE ROAD. I TRIE TO RESTART THE CAR, THE STARTER MADE NOISE BUT THE ENGINE WOULD NOT TURN OVER. I CALLED ROADSIDE ASSISTANCE AND DID THE THREE TIME LOCK AND UNLOCK ROUTINE, AND THE CAR WOULD NOT START. AFTER TOWING THE CAR BACK TO THE SAME DEALER, THEY TOLD ME THE CAR WAS SHOWING NO CODES, THE ISSUE COULD NOT BE REPLICATED AND THE CAR SHOULD BE FINE TO DRIVE AGAIN! I'M NOW AFRAID TO DRIVE THE VEHICLE, AND THE DEALER IS REFUSING TO FIX IT.

THERE'S A CONSTANT GAS SMELL IN MY CAR. THE DEALERSHIP CLAIMED IT WAS A LEAK TWICE, BUT THAT CAN'T BE THE PROBLEM BECAUSE IT STILL CARRIES THE SMELL.
