Other Fuel System Tank Filling/charging problems of the 2003 Mercedes Benz E55

Bought a pre-owned 2003 E55 from mercedes dealer 2005. Have had car serviced regularly and exclusively at dealer ever since. Have smelled gasoline smell in garage especially after filling-up car. Most recently, on 21-Apr-15 check engine light lit. Took car to dealer. Dealer said gas tank leaking and they would fix it - courtesy of mercedes-benz - no cost to me. . Read more...

After filling up gas tank, fumes filled the cabin. I lifted the rear seat and exposed the driver's side gas tank sending unit & there was a gas puddle surrounding the ring. This leak, according to posts, seem to be a common problem.

Strong odor of gasoline in the interior of the car after filling the tank. Odor has persisted for a week. Refer to NHTSA action number pe12001.

Reference the NHTSA action# pe12001 there is a fuel leak at one or both of the fuel sending units and at one or both of the fuel pumps located in the gas tank of this car. When filling the gas tank to full, gas leaks and produces a very strong gasoline smell inside and around the exterior of the car. I have removed the rear seat to gain access to the units and I have observed standing gasoline on the top surface of the sending unit seals. There are electrical connections inside of these units and they appear to have been shorting due to the leak. This is potentially a very hazardous, life threatening condition.

I began to notice strong odor of gasoline in my garage intermittently - I park the car in garage daily but only noticed gasoline odor some days- took to dealer Dec 2012 and dealer stated there was fuel leak at fuel rail pressure regulator - dealer replaced fuel rail and regulator- I thought problem was resolved since I did not notice gasoline odor for a while- then started to have intermittent gasoline odor again- noticed small oil leak under engine and took it back to dealer Feb 2013 and mentioned that I smelled fuel odor again- dealer located minor oil leak at rear main seal that did not need immediate attention and did not comment anything further about the gasoline odor- I monitored the situation for next few weeks- months since I did not have time to keep taking auto back to dealer - finally figured out that intermittent nature of gasoline smell was related to filling tank- noticed the odor after full fill-up,then stopped after few days- no odor if just fill up 1/2-3/4 tank.

Upon filling the fuel tank, there is an obvious odor of fuel which is noticed outside the vehicle but difficult to pinpoint where it's coming from. I went to the dealer and they said all the recalls or safety recalls were performed on my vehicle already. But the odor of gas is very strong and not resolved yet.

Please reference the NHTSA action# pe12001 spontaneous fuel leak from the top of the tank upon filling up. Took car to dealer, they stated fuel noted on top of tank. Required fuel sender unit replacement, not under warranty.

Fuel leaks from tank when it is filled to the top. Car has been to dealer and had fuel tank seals replaced twice. Fuel pumps, gauge and hose system was also replaced for $1,500. Strong odor of gasoline if the car is parked in my garage after filling tank. I kept the pump assembly as a souvenir and see that many parts are brittle and prone to cracking. Materials in fuel pumping system appear to be inappropriate for driving in hot florida climate. Car has been kept in garage since new (except after filling gas tank).
