Seven problems related to other fuel system have been reported for the 2003 Mercedes Benz E500. The most recently reported issues are listed below.
"takata recall" each year it fails the emmission test the failed code is po456. I had an evap system test ran they said it was a problem with the purge valve, eval hose, and the filler neck. (leaks). In my own words, the engine comes on and off, the computer is indicating that the truck is open when it is not, the seatbelt tighten up and makes a clicking noise while I'm driving, and sometimes I can't get out of the car it locks me inand I have to push the unlock button on the dash, and the alarm comes on whenever! and the tire pressure indicator stays on and we recently had new tires put on. We had it balanced and an alignment done as well. Other than that the car is still driving well. I thought benz was one of the best vehicles but I'm not so sure about that now with these concerns! these things happen when in motion except for the alarm going off. I think there may be a problem with the fuel system and I hope this car don't blowup on me! s royster.
My car has a strong and overwhelming smell of gas inside the car when I drive. This has been happening for 2 weeks now whenever I drive with the windows up. I am forced to drive with the windows down in order to breath.
Fuel leaks and fuel fumes in cabin.
After refueling my E500 (filling it up), driving it home and parking it in the garage, shortly afterwards there was a very strong gasoline odor in my home. I have an attached garage which unfortunately has a piece of door facing missing from the side entry door, which is how the fumes flowed into my attic and through the ac vents throughout my entire home. The fumes were so intense I experienced chronic coughing, headache, and itching around my eyelids. The local gas company came out and performed their normal routine only to inform me it wasn't natural gas nor carbon-monoxide. As he checked the hot water heater located in the garage, he immediately stated it was my car. I could smell gasoline fumes around my car as well as inside. It was so strong, I left my car outside the garage over night, raised the garage door (both doors), opened all windows in my home and shortly the fumes had dissipated. I have reported this to mb corporate customer care and waiting to see what assistance they will offer me as my car is out of warranty, but for the benefit of owners who still have warranty vehicles, there needs to be something done by the dealership. This is a very dangerous situation and the repair burden should not be the responsibility of the owner. I am making an appointment with the dealership to get a diagnosis. It is my hope mb will do the right thing.
Car smells of gasoline in the rear driver side. You can smell it outside of the car also. After reading the message boards on this issue, it seems like mb should fix this issue at no cost to owners.
Tl- the contact owns a 2003 Mercedes Benz E500. The contact stated that while parked, there was a strong fuel odor around the vehicle. The vehicle was not taken to the dealer for a diagnosis. The manufacturer was not made aware of the failure. The vehicle was not repaired. The approximate failure and current mileage was 100,000. Mah.
Fuel fumes were detected during routine maintenance at an authorized Mercedes Benz repair facility. Investigation revealed fuel pooling on top of the fuel filter with integrated fuel pressure regulator. The original equipment defective part number is 3114704094 and has since been superceded. It was determined that there was a leak due to a crack in the plastic assembly. The authorized Mercedes Benz mechanic identified the problem as to similiar to the one that resulted in Mercedes Benz voluntary emissions recall campaign #2008-020001. Vehicles included in the recall were model year 2003-2006 e class and 2006 cls-class vehicles. After contacting Mercedes Benz customer service about the problem they stated the recall only applied to the amg version of e class vehicles and my VIN number was not included in the recall. On March 19th, a USA today article reported that NHTSA was expanding an investigation of the merceds benz fix to the recall problem beyond the amg version of e class vehicles. I believe my vehicle is expericing the same problem that affected the amg versions but Mercedes Benz does not. I'd like this complaint be included in the population of e class vehicles being reinvestigated by NHTSA with similiar problems with the fuel filter with integrated fuel pressure regulator.
