Gas odor when tank is full
Leaking fuel sensors on Mercedes Vehicles...
Everyday I run into more people with this problem the dealers and Mercedes Benz Corporate are a$$holes about it .If you are lucky they may cover half of the parts and charge you the labor to repair/replace the leaking sensors. Just hope that your gas tank does not need to be replaced. They are getting hundreds of calls a day on these Leaking tanks and sensors. This will end bad for Mercedes One day in the near future someone's house is going to burn to the ground because of leaking Fuel in the garage next to the water heater.



My wife had the problem in her CLK550 2007 The dealer Fletcher Jones of Newport Beach Gave us nothing but trouble and getting the problem fixed her car has 7000 miles on it.
Shame on Mercedes Benz of America and Fletcher Jones Motorcars of Newport CA
For NOT doing the right thing for their Customers. This is a Serious fire and explosion Hazard. The fix can run 1300 dollars all the way up to 3500 dollars if you need a new fuel tank. The estimates online say that as many as a million vehicles are using these defective Sensors (I think it is a lot more)
Keep in mind these sensors are located directly under the rear passenger seats under a access panels. In my wife vehicle we actual smelled the gasoline in the cabin and the garage. Also note all of the leads and electrical lines going into this sensors in contact with the raw fuel/gasoline.

Hit them were it hurts on Social Media

Just wondering if your 1997 C230 was ever fixed due to its fuel odor problem? I have exact same model and year and it's everything they say here in the thread. I'm finding the NHTSA are only covering the E class but in every case it has to be the same in all of their models.
It's got a very strong odor that will seep up to my 3rd level condo from the garage. My boyfriend was so worried he told me to park my car outside. I only fill my tank 3/4 full from then on because of this issue. Thanks for your reply!

Your car likely has different problem as the above apply to specific tanks under rear seat.
Cost the question in your class section and they should give you precise advise.
With fuel leak I would not drive the car at all and your boyfriend is right to park the car outside.
18 years old might have lot of aging components, so take it to qualified shop ASAP
****, that time spent reading was wasted typing all this crap. Damn it.


Before I took it to them I lifted the rear seat and removed the covers where the fuel pump sit's, there was gas on top of the tank.
At the time, the 3rd party extended warranty did not approve of an OEM tank, only a off branded one, so a major chunk of change was out of pocket. Guess I need to file a claim, since I just found out about this letter.
The tank started leaking again this week. I may be out of luck this time around, since I am beyond the 15 yr period (Oct 2003 delivery). Seems like this tank only lasts about 8 years at a time, which is very disappointing.
