My car went into limp mode. Well after I spend 2000. And 2 years trying to figure out what was going on with my car. Come to find out. Water was getting in and it messed up my whole system. I just put every part on this car is brand new. Trying to figure this out. Now for nothing. I read somewhere. That I'm not the only one with this issue. That mercedes. Needs to make it right. What do u think
Everytime I fill the gas tank I smell gas strongly I paid out of pocket to have the fuel pump done the gas cap the purge valve and I’m still getting a check engine light for a evap leak and still smelling gas from inside and outside the car I also have a rattle noise comeing from inside the gas tank u can take the gas cap off and heat it inside the gas tank from outside and inside the car it’s a constant knocking noise inside the gas tank I replaced everything and their is still a knock noise and fuel smell I have proof receipts from Merceds dealer of all work I did and I have videos of the noise I can’t afford a new gas tank I bought the car in Connecticut with a 2 year extended warranty the warranty place won’t cover a new gas tank I saw their were recalls for gas smells on other models same year as mine but not the c class a lot of other people I noticed on google have had this same knocking noise and fuel smell the car only has 70 thousand miles on it I can’t afford 5 grand for a new gas tank and labor espically after I already paid for all this stuff and already had this problem diagnosed but yet everytime I get my car back it’s never fixed but they tell me it’s fixed they have my car for months at a time and never give it back to me fixed I’m always paying for rental cars because of this they won’t supply me with a loaner please put a recall in for these fuel tanks 2007 c280 4 matic only has 70 thousand miles I bought it 4 months ago and no one will fix this properly for me when they have diagnosed this problem multiple times the rattle is the baffles in the fuel tank they keep working their way around it and keep telling me it’s other things just to get my money instead of properly diagnosing it I’m just sick of geting my car back saying it’s fixed when it’s not out of the 4 months I’ve had this car it has Ben in my possession for maybe one of them the other 3 months it’s Ben in and out the shop for the same problem please recall these tanks car has low miles
After filling the gas tank over the three quarters(3/4) mark, there is an extreme of gas. No leaks are seen and a garage found no leaks. The odor is so bad/strong that the car can not be placed in the garage. The odor remain until the fuel level is at or below the three quarters level.
My 2007 c230 has a problem with the smell of gasoline when you fill up. I have seen alot of complaints about the gas tank and its system on line. An when I talked to medcedes I was told they have had alot of issues with the mercedes in the past and that issue. They replaced alot of them at one time I dont know which model. I have seen alot of people with my style of mercedes with similiar issues. This type of thing should be taken care of by the dealer.
CAR LEAKS FUEL UNDER THE SEAT. *TR
WHEN I FILL UP WITH GAS, THE CAR SALON FILLS UP WITH THE GAS SMELL. THE PROBLEM SHOULD BE IN THE FUEL PUMP OR SO. THE SMELL IS PERSISTENT IN THE GARAGE. WHILE DRIVING, I DID NOT NOTICE. WHEN THE AMOUNT OF GAS IN THE FUEL TANK DECREASES, THE SMELL GOES AWAY. I REMOVED THE BACK SEAT AND SO THE GAS RESIDUE OVER THE PUMP.
WHEN THE FUEL TANK IS FILLED THERE IS A STRONG GAS ORDER COMING FROM THE VEHICLE.
WHEN RESEARCHING MY PROBLEM I FOUND THIS TK HE A COMMON PROBLEM. IF I FILL MY GAS TANK IT LEAKS GAS. THE CABIN OF CAR IS FLOODED WITH FUMES. SO MANY WITH SAME CAR HAVE COMPLAINED ABOUT THIS.
I have an issue that when you fill up the car you will smell a strong gas odor outside of the car. as soon as the fuel level drops down the odor gets less and less. looked under rear seat and no fuel leaks. also i see a lot of posts about this same issue with this same type of car. 2007 c230 sport. please look into this. i even changed out gaskets and fuel pumps. just in case.
SEVERAL TIMES I'VE FILLED MY GAS TANK I GOT A STRONG SMELL OF GAS BEFORE ENTERING MY VEHICLE. I HAD THEN MADE SURE NOT TO FILL THE TANK UP DUE TO THIS LEAKAGE. I BELIEVE ITS VERY DANGEROUS. THE SMELL DOESN'T GO AWAY UNTIL I DRIVE THE CAR FOR SEVERAL DAYS.
WE JUST BOUGHT THIS CAR. AFTER I FILLED IT UP, THERE IS STRONG GASOLINE SMELL IN THE GARAGE. PARKED THE CAR OUTSIDE AND IT STILL HAS SMELL. IS THIS A COMMON PROBLEM WITH MERCEDES BENZ C280? UPON FURTHER RESEARCH, THERE WAS EXTENDED WARRANTY FROM MERCEDES TO COVER E CLASS AND CLS CLASS FUEL ODOR ONLY. WHAT ABOUT THE C CLASS CARS? DON'T BELIEVE THIS IS THE WAY THE CAR SHOULD BE PERFORMING. BY THE WAY, THE CAR IS 2007 WITH 102K MILES. I BELIEVE MERCEDES SHOULD ALSO COVER C CLASS FOR THE SAME PROBLEM,
LEAKING FUEL FILLING HOSES
NHTSA RECALL 08V303000. MY CAR FUEL GAUGE MISREADS WHAT IS NOT THERE. STALLS AND NOT RESTART WITHOUT TAPPING THE FUEL PUMP. FUEL LIGHT INDICATES FUEL SENSOR NEED TO BE REPLACED.

IMPACT OF ACCIDENT LOST FUEL. SINCE ACCIDENT TOWED THREE TIMES STALLED AND TOWED ONCE AND TWICE BY MERCEDES BENZ. REPLACEMENT COST $1051.00.
AT LEFT TIRE AREA, LEFT FUEL SENDING UNIT LEAKING FUEL, AFTER FUEL FILL-UP
VERY STRONG ODOR OF GASOLINE FILLS THE GARAGE AND HOUSE WHEN THE VEHICLE IS PARKED INSIDE AFTER FUELING TO FULL TANK. THE GASOLINE ODOR IS SO STRONG THAT I FEEL IT IS UNSAFE TO PARK THE VEHICLE IN THE GARAGE BECAUSE OF THE FUMES, AND THE POTENTIAL FOR FIRE
FOR LAST THREE PLUS YEARS, WHENEVER GAS TANK IS FILLED OVER THE 3/4 FULL MARK THERE IS A HEAVY GAS ODOR BUT I HAVE NOT SEEN LEAKING GAS. I ONLY PUT IN LESS THAN 9 GALLONS OF GAS AT A TIME FEARING AN EXPLOSION IN MY GARAGE WHERE WATER HEATER IS LOCATED.
ONE WEEKEND WE WOKE UP IN THE MORNING TO GO WASH, AND AS SOON AS WE OPENED OUR DOORS TO THE VEHICLE A STRONG ODOR OF GASOLINE CAME OUT OF THE VEHICLE. INSIDE OF THE VEHICLE AND IN THE TRUNK IT SMELLED A LOT LIKE GASOLINE, IT'S BEEN LIKE THIS NOW FOR ABOUT 4 DAYS AND THE ODOR IS STILL STRONG. IT WORRIES ME BECAUSE I HAVE KIDS. WE'VE BEEN DRIVING AROUND WITH OUR WINDOWS SLIGHTLY DOWN, EVEN AFRAID TO TURN ON THE HEATER OR AC
WITH FULL TANK, GAS SMELLS INSIDE AND OUTSIDE.
STRONG GASOLINE ORDOR COMING FROM LEFT REAR WHEEL WELL EVERY TIME THE CAR IS REFUELED. THE STRONG ORDOR LINGERS ON FOR 2-3DAYS FILLING THE GARAGE AND HOUSE WITH FULE ORDOR. SEEMS TO BE THE SAME PROBLEM AS E CLASS, WHICH IS UNDER AN EXTENDED WARRANTY FOR THE FUEL ORDOR ISSUE. MB SERVICE REP SAID THAT C CLASS VEHICLES ARE NOT COVERED BY THE EXTENDED WARRANTY AND OWNERS ARE RESPONSIBLE FOR THE COST OF REPAIR.
