2007 Mercedes-Benz E350: wrong fuel gauge reading

Filed Mar 23, 2023 · Fuel system · CA

Fuel sending unit warranty was extended but only for a short time. Mine has failed and gas is leaking into the car and MB won’t honor warranty because it expired on my car and entire fuel tank has to be replaced.

When I fill up the gas tank I notice a gas smell from outside of the car on the rear drivers side. When the fuel level drops to 3/4 full the smell disappears. I'm afraid of an explosion if I park in an enclosed garage

Strong gas odor when tank filled up. Keeping fuel level at only half tank do not smell - but when fuel up to full or close to it strong odor is back.

Pungent fuel odor after filling up gas tank. The smell is so strong that it causes drivers nausea, headaches, and dizziness. Local dealer (rbm of alpharetta) states: "my tech found the fuel sending unit sealing ring to be cracked and leaking when he pulled up the back seat. Then he got the vehicle up in the air an could see fuel residue on the back side of the fuel tank that had dripped down from the top. The solution for repair is to replace the fuel tank assembly, reason for this is your vehicle is a pzev or partial zero emissions vehicle. The fuel tank and sending unit are sealed from the factory for zero emission standards. When you arrived this morning I reviewed the vmi for your car to show you it was not part of the warranty extension for the fuel tank you spoke of. I still ran coverage for your vehicle to see if mercedes would cover the repair but it is outside the warranty period for this repair." I'm not sure of the integrity of mercedes-benz, but I will soon find out. This is obviously the exact same problem experienced on the vehicles under the warranty extension issued by mbz, but since my vehicle was originally purchased in california (pzev), they are denying the claim. I'm assuming this is due to the fact that the repair cost is much more significant than the traditional (non-pzev) design. The pzev vehicles need the entire fuel tank replaced versus the simpler (and less expensive) fuel sending unit for the non-pzev cars. Otherwise, this is the exact same problem...only a different fix. This is a significant safety issue admitted by my service advisor. He stated, that the car is dangerous to drive in the current state. I am currently escalating with mbz leadership and hoping they will hold integrity as a business and do the right thing and fix it under this extended warranty.

I believe there is a leak in my fuel sending unit. First, the tank level indicator circuit is unreliable below a half tank. Secondly, after I top my fuel tank off, the car will run out of gas after using 19.5 to 20 gallons. The tank is 21.5 gallons.

My 2007 mercedes benz e350, began to smell of fuel on the inside after a fill up. I took the vehicle in to find out what the issue might be and was informed that the fuel sending unit was not operating properly. The vehicle was repaired, however, the smell of fuel still lingers in the vehicle. I have left the windows down for days at a time month after month. I went an obtained some industrial strength aerosol and the smell still has not totally left the vehicle to date.

[this is only explaining the first occurrence, this has happened a plethora of times since] after stopping at a fuel station and filling the fuel tank from 1/4 to full, we drove on a local road at an average speed of about 30mph for approximately 3 miles. After this we merged onto a major highway where the average speed we were going was between 60-75mph. It was after driving at these speeds for 10 minutes that we started to smell the odor of gasoline in the cabin. Without any other cars in front of us or any noticeable spill [on the road] that we may have passed, there could not have been any other origin of the odor except for the e350. At first it was a low odor of gasoline emanating from under the front passenger side seat, but soon a strong odor of gasoline filled the entire cabin, to the point of forcing us to roll down the windows. The smell did not go away completely but rolling the windows down to allow fresh air to purge the cabin did help. We have taken the car into the dealership multiple times and have requested a complete check-up of the vehicle. The dealership (euro motors of devon hill, pa) has told us that there is nothing wrong with the vehicle (fuel system wise). However, after refueling [especially from the tank being at 50% and then me filling it to 100%] the strong odor returns inside the cabin. It goes away after the fuel levels have dropped from a full tank to 3/4 full, after which the odor does not return when driving the car. I have just heard about other having the same issue and thought I was paranoid. However, it seems that this is endogenous between all other e350s. Please feel free to contact me regarding any diagnostic data that would help you get to the bottom of this.

After I filled up gas and parked for 2 days, I went back to the car and smelled gas odor from the outside and the inside of the car. I drove the car for 78 miles and still smell the gas while driving. I went back and parked, the smell still occurred. When I checked online, there was a lot of complaint about this issue ( fuel sending unit) on this car (mercedes benz wagon 4matic e 350. 2003-2009. ) the gas sending unit has leaked. I think this is a safety issue that the federal safety agency should open up the investigation and conduct a recall about this issue, because I have two children's of my own that sit in the backseat of our vehicle. I will take no chances to drive this vehicle and we still own a payment on it. If this issue is not being investigate, I will take it up to the next level ( national television). I hope this issue will resolve at this level immediately . Thank you [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
