After filling up the gas tank, there was a strong fuel odor in and around the vehicle. The dealership diagnosed the problem as a defective fuel sending unit/pump top cover.

All of a sudden, one day after filling my tank, there's now an overwhelming gas smell present both ~20 feet away from vehicle, and inside the car. It is so bad, I have to leave windows down for 20-30 minutes while driving before the environment becomes tolerable with the windows up. I have read that other similar E350 models have this problem, but my newer (2011) year model doesn't appear to be on the extended warranty repair list. I believe I have exactly the same issue others have described because the smell of gas is very strong after a top-off, and gets gradually better, becoming much less noticeable as fuel tank level approaches 1/2 tank and below.

E350 6-cyl

  • 80,000 miles
Adblue heater/senor for the emission control on the 2011 Mercedes-Benz E350 bluetec fail after 80,000 miles the problem with the system is that it starts a count down which is displayed on the dash to how many starts are left before the car completely shuts down and will not start because of a heater/senor. So here I am held captive by the number of starts I have left to get the car to a dealership to correct the problem. My problem with this is a $50,000 plus car shouldn't be shutting down for a emission control system.
