Eight problems related to other fuel system pump have been reported for the 2005 Mercedes Benz E320. The most recently reported issues are listed below.
8/4/16 vehicle had strong smell of gas inside after fillup. Went away after half full. Noticed recall in online doc's and took to mercedes of san diego where tank mod, cable harness, bracket, seal ringx2, insulation under seat were replaced no charge under warranty. 6/20/17 vehicle quit when approaching residence. Then wouldn't start but cranked. Same symptoms next day. Towed to mb san diego diagnosed fuel pump components failed $1,000 w/no offer to cover under recall. I further reviewed same internet doc's which show fuel pumps, filters, fuel level senders are covered under mb 15 yr. Unltd miles warranty. Will call service writer in morning to advise they should cover repairs, tow plus rental car while I was researchng.
The car has fuel (gasoline) vapors inside and outside of the car. The fuel sending unit or the fuel pump in the saddle gas tank under the back seats leaks gasoline and the smell makes me sick. I am afraid the car will explode if the vapor is present at the combustible ratio of gasoline to air.
Sensed strong gas odor at fill up. Investigate online and found that this car has this known issue but it is not a recall. ? had mb mechanic look and found leaking gas under rear seat near fuel pump.
I brought my 2005 mercedes E320 [purchased oct. 2014] in for an oil change Jan. 30, 2014. I mentioned to the service person a noise [like something broke] I heard while out of town visiting. He changed my oil and also found/replace a broken rear suspension spring. This occurred within 3 months of purchase. Repair cost: $551. 17. My second incident occured Feb. 19th. I noticed a puddle of fluid underneath the vehicle [not sure what kind of fluid] and immediately brought the car back to the dealer for service. I was told the transmission servo solenoid seals required replacing. Repair cost: $157. 84. The third incident was reported Apr. 21, 2014. I noted an increasingly bad odor inside the car since the first day of purchase, but wasn't sure exactly what it was as I was still trying to identify it. I finally realized it was gas I was smelling [intermittantly] inside the vehicle for the last six months. It turned out to be leaking fuel from the left fuel pump seal (lfps) underneath the rear seat. Repair cost: $161. 31. The fuel odor got worse after the replacing the lfps. Most noticeably after filling the car with gas. I've also identified gasoline leaking from the drivers' side rear quarter that puddled by the tire. My feeling at this time, repairs may be onging for my E320, that I really like.
We start notice gas fumes smell when we filled our mercedes-benz up with gas & as we drove our vehicle the gas smell would stop, approximately 30 miles plus. As the months went on the incident would get worst at each fill-up. Sometime around February the check engine light came on so we took the vehicle to repair shop & they found gas leakage around the fuel pump under the back seat. As of today the issue is still going on with the gas smell.
The fuel pump and/or gasket is leaking gasoline into the area under the back seat on the drivers side. The first time we noticed the problem was on Nov 1, 2012, but it has happened several times since then. We can no longer fill the tank to the full position without fuel leaking. We have replaced the fuel gasket, but it has since leaked again. This is a great safety concern to me, and it should be corrected by Mercedes Benz at no cost to me.
The contact owns a 2005 Mercedes Benz e-320. The contact stated that the rear seat was filled with gasoline. The vehicle was taken to the dealer for inspection where the contact was informed that there was an issue with the fuel pump. The fuel pump was replaced. The vehicle was repaired. The manufacturer was notified of the issue. The approximate failure mileage was 80,000.
When the fuel tank is filled 100% there is a very strong fuel odor, which can be smelled in the outdoors but is extremely strong when parked in the attached garage. This odor is so strong that it enters the house, and we have to leave the garage door wide open for fear of a spark causing a fire. If one looks under the car there is no dripping. The odor does not go away until the fuel tank is no longer completely full. The fuel leak stops after we are down a couple gallons from completely full fuel tank. I have pulled the back seat and seen that the there is gasoline pooling around the fuel pump (fuel delivery module). I am concerned that a rear end collision would cause the leaking fuel to combust.
