Leaky fuel sending unit. I brought my 2008 e63 amg into mercedes of boston for to repair a leaking fuel sending unit around the spring of 2015. I realize this was an issue for many e class and was being investigated by the federal safety agency. I specifically asked my service advisor if mercedes was at least covering part of the repair. He said there was no warranty coverage on it. I paid $900 for the repair. I just found out on the federal safety agency that mercedes gave an extended warranty coverage for fuel related parts for 15 years as of september 2014. Mercedes is deliberately hiding these details from consumers. No notifications was ever sent. No refunds offered.

After refueling my car's gas tank I began to notice some sort of gas leakage. It's especially pronounced when the car is parked in the garage since the fume is unmistakable. There is apparently a fuel leakage near the rear tire (driver's side). I'm concerned that if there were anything in the garage that is ignited it would cause some terrible incident. After I brought my car in for service I found out that the fuel sender unit needs to be replaced along with a related gasket. This type of problem should not experience failure at this low mileage.

When I fill up the fuel tank to full, I smell a strong scent of gasoline inside the car. The fuel is leaking somewhere until I burn it down to about a 3/4 tank full.

Fuel leaking from fuel sending unit and puddling on top of tank. My whole garage is full of fuel vapor! Not to mention if it contacted a hot part on the car. I just found out this is a "known issue".

I purchased this car late july 2012 and when I went to pick it up I noticed a slight smell of gas from the left rear of car but, didn't think much of it as it was a new to me vehicle, just thought it was freshly filled up. The next time I filled up I noticed that the car smelled both inside the car and outside the car. As a new owner of a newer mb I joined mbworld form and searched this problem with e55 and e63 and found that it is a common problem for the w211 cars. Also, it seems the solution is not as obvious as one would think. On nov 14, 20012 I took it to cal star motors in glendale ca (a mercedes dealer) for repair, they told me that the cause of the problem is the seal between the sending unit and the gas tank. They replaced this part and I drove the car home as I needed to bring in car with half a tank for repair I did not notice any issue. Next time I filled up there was no smell from inside cabin and only slight smell outside. I now have filled up several times and the problem has returned. I should say that after fill up there has never been any leaked gas present when parked as I check drive daily for any evidence of leaks in any fluid. I feel that if there is a gas leak issue with this/these cars which it appears there is based on so many issues reported that mercedes has a responsibility to solve the problem as it is a very dangerous situation to leave unresolved.

Filled my car up with gas and after driving it home there is a very strong fuel smell coming from the car. Looking online I see that many people with the e63 amg cars have also experienced this, and it is a faulty fuel sender unit that is literally leaking fuel out.

I reported to my independent mechanic a strong fuel smell when filling the vehicle full and parking it. Upon further investigation, my mechanic discovered a fuel leak from the drivers side of the tank onto the left exhaust which of course can create a fire hazard. I immediately contacted my local mb dealership and spent days trying to get in touch with the service manager. Finally after contacting the mb central region office, I left a vm and was contacted by the service manager I had been trying to get in touch with. As of today 4/8/13, I took the vehicle in for inspection. They told me that the drivers side fuel sending unit/pump is leaking and would need to be replaced. I asked if the car was safe to drive, they replied no, but happily sent me on my way anyhow. This problem lines up with every other complaint about the my03-09 w211's that exhibit this problem. I have not had the fuel leaking to the ground and pooling up, but the dealership has confirmed that the sending unit is indeed leaking and pooling up in the depression where the sending unit attaches to the tank, which is now leaking onto my drivers side exhaust, thus creating potential for a fire hazard. The federal safety agency action number: ea13003.

I had just purchased the car the day before (april 28, 2012). When I filled the fuel tank, I notice a strong smell of gasoline. This has occurred every time I fill the car with fuel. At first I thought it was a fuel injector leaking down and something I would have to address in the near future. However, last week I went to drive the car after I had just filled the tank with fuel. The car was in my garage and the smell of gasoline was very strong. I noticed a puddle of fluid in front of the left rear tire. My first reaction was it was condensation from the air conditioning system. I bent down to look at it and then I notice a separate condensation tail coming from the middle of the car. I sampled the fluid stream from the middle of the car and indeed it was water. However when I looked at the other puddle, I notice a constant and rapid drip coming from the shield under the gas tank. When I sampled the puddle it was pure gasoline. This was most disconcerting as this fuel leak is very close to the exhaust and the brakes. Either one of which could ignite the fuel. I am a mechanical engineer with considerable auto racing experience, so I know how dangerous this can be. I called mercedes benz of sugar land on monday (11/12/12) and talked to a service representative. I told him of the fuel leak and he told me there was no reported issues and no service bulletins for such a problem. I was also told to bring the car in and they would repair it at my expense. Having paid my way through my first degree as a mechanic as well as designing racing equipment for ford motor company, I believe this should be covered under warranty as part of the emission system. This is of course secondary and in addition to the obvious safety hazard this condition presents.
