Everytime I fill my fuel tank I've noticed a strong fuel odor. Upon inspection I have found the fuel tank to have traces of fuel on the exterior of tank, so my tank has a leak somewhere.

Car was not moving when we noticed a strong odor of gasoline coming from the rear seat area, when we pulled into our garage the odor was so strong we moved the car to the outside to prevent a possible fire in our home, I called the dealer and the service manager immediately told me that he thought the gas tank sender/sensor was leaking and possibly that both sensors were leaking and possibly the tank. He also told me that gasoline could be pooling on top of the gas tank causing the odor. He later called me and confirmed that all of the above had happened and could be repaired for approximately $3250 I ask if this was a recurring problem on this model he said that there were no recalls or warning but they had seen this problem before. I then went on line and found a lot of blogs describing my problem almost identically. In my opinion this is a serious defect in the construction of this car and could and probably will cause serious injury and possibly death to some one riding in this model. I believe there is enough evidence in the recurring blogs that Mercedes is quite aware of this serious safety problem and are probably ignoring this very expensive fix, please do not ignore this complaint until someone or several are hurt or killed.

The vehicle has the smell of gas venting into the passenger compartment and concerned for passenger safety. Currently the vehicle is not properly meeting or complying with epa regulations concerning proper emissions of fuel ventilation and has gross product safety issue concerning passenger(s) inside the vehicle. The fueling system is venting improperly and fuel sender is not sealed properly. Car has never had problem until current date of filing. Aware of current Mercedes corporate legal response to your enquire however the system has never been worked on (by Mercedes dealer) nor is this just a minor issue with low vehicle count. Please protect me and my family concerning this issue! [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

There is a strong fuel smell in the vehicle after filling up gas tank. Mercedes Benz dealer found the issue associated to left side fuel sending unit, which seem to be a recurrent issue with this model in Mercedes. Dealer requires $875.34 to fix the issue. I have contacted mbusa to see if they can help with this repair. In 2008 there was a voluntary recall #2008-020001, on some E and cls class for 03-06 vehicles, however I was told my car VIN is not part of this recall. Web forums of Mercedes Benz owners are filled with same complaint for all E class models with chassis W211. Please investigate this issue. I understand there is an open NHTSA case PE12-001 that may be related to my complaint. Thank you for your prompt attention. This is my second Mercedes W211 model vehicle with the same issue.

Noticed a strong gasoline smell in my garage and inside my vehicle. Also noticed that my left rear passenger seat was discolored with dark yellow staining. Check engine light appeared on car and took to local Mercedes-Benz dealer to check problem and was told that the fuel sending unit had failed and that raw fuel was leaking in passenger compartment causing the gasoline odor and staining to upholstery. Was strongly urged by service advisor at Mercedes-Benz to replace the sending unit "anytime you're leaking fuel that's a safety issue". had sending unit replaced as advised and was told to keep windows down to air the car of gasoline fumes. Mercedes- Benz attempted to clean upholstery however this was unsuccessful and will likely need to be replaced.

After filling my car with gas a strong odor of gasoline is present. You smell the odor from both inside and outside of the car. After the gas goes below about 3/4 of a tank the smell is no longer present. I have read several online complaints of other owners of this vehicle having the same issues.

I came out to my garage one morning to find a my car wreaking of fuel. I decided to drive the car around for a few to see if it the pungent odor would go dissipate altogether. During this time, I took it to my mechanic to let him do a quick once-over before he left for the day. He stated that there was fuel leaking onto my exhaust. Being that he didn't have the tools and whatnot to replace the sending unit, I had it towed to Mercedes Benz. I was not going to let my girlfriend drive the car to the dealership. No way, no how. Skyland automotive(my local mecedes Benz dealership) found a puddle of fuel under my back seat. They replaced the fuel sending unit partially under my third party warranty. I, however, had to pay roughly $500 out of pocket. I have heard of this issue happening on many W211 E class cars, it has happened to some more than once. I'm at 7X, xxx miles now and definitely don't want to have to go through this again. Fuel leaking onto the ground is bad enough, but leaking onto my exhaust isn't to be tolerated. It's downright dangerous. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
