2005 Mercedes Benz E500: check engine light

Filed Jul 22, 2025 · Engine, Fuel system · CA

Car smells like gas. Constantly a couple machanic. Did some repairs. But there’s a small leak as well from a smoke test. Gas leaks in more than one area. Oil leaks everywhere. Evap leak didn’t pass smog. Then went to a smog station and repair. Check engine light back on again. I saw Mercedes had an extended warranty to avoid recalling several safety complaints. I got the car from a guy who never looked into recalls or extended warranty for these complaints. Please help me to get refunded what I payed so far with repairs on gas leaks. Also to repair the whole gas system. It is dangerously ongoing. I never got notified by Mercedes nor did the previous owner.

A couple weeks after my brake hydraulics went out (which was repaired under warranty) I started to notice a strong gas smell from inside of my car, along with a check engine light. After a couple weeks of airing out I decided to take it in to mercedes benz of littleton for repair. I was charged $1500 for the repair, which still left my car smelling like gas and check engine light came back on with the same error code(small evap. Leak) I lifted the back seat to find the bottom soaked in gunnky gas along with electrical wires running through the leak area. I'm afraid my car will catch on fire or blow up. I'm sick of these dangerous malfunctions that I feel mercedes knows about but won't repair for free. I asked the service tech what I can do to prevent this from happening and he said "nothing". Now I'm $1500 in the drain and the problem is not fixed, and I was reassured the problem would show up again.

I took my car 2005 e500 for regular maintenance at the dealer and was told the ball bearings needed to be replaced in july 2011. Then after checking everything out, the dealer told me the fuel ring under the seat needs to be replaced. Cost usd 600. Also there was gasoline seeping out of car onto the driveway when car was parked. I started smelling gasoline smell in march 2012. I took the car again to the dealership in july 2012 and this time they replaced the fuel system. Cost usd 2100. There were puddles of gasoline in my garage after the service. I was told there might be gasoline smell. After the smell lingered after every fillup I took the car back to dealership. The dealership again wanted to charge me usd 3000 for the fuel leak but I told them I just fixed the fuel leak problem. This was in sept 2012. This time the dealership didn't charge me anything. I again took my car to the dealership for a check engine light that came on in sept 2013 to mercedes benz in grapevine, tx. I was told there is a leak in the fuel tank and the cost is usd 2115. I told the dealer about the federal safety agency investigation, class action lawsuit for the fuel system on mercedes e500 vehicles and the service advisor, matt pinecrest, told me the case was settled and mercedes won. This is obviously a falsehood. This problem has now taken an emotional toll on me since I can't drive my car properly without worrying.

Fuel pump / sender fuel leak under rear seat. Has gas smell after getting gas. Check engine light comes on with gas cap warning light constantly, especially if add gas more than 3/4 tank. Over the years (I still own the vehicle), even with 1/2 tank gas the gas cap warning light would come on from time to time, especially in hot weather. Dealer hasn't been able to fix issue since I bought car as cpo in 2008. They told me to replace gas cap. Replaced, no impact. I opened up the rear seat and can see gas stains in the fuel sender/pump cap area with some residual gas.

2005 mercedes benz e class has fuel tank issues. Many owners have reported the same issue 2 to 3 years after purchase. First the fuel cap indicator comes on, later triggering the engine light to appear and upon repair attempts everything but the fuel tank is suspected. The end result after adjusting and tweaking many other parts associated with the fuel evap system, replacing the fuel tank resolved the issue. This is unsafe. A few owners reported a filter valve connected to the fuel tank under the back seat actually getting hot, very hot while driving. Please let's not wait until loss of life forces us to act!!!
