Three problems related to other fuel system tank assembly have been reported for the 2005 Mercedes Benz CLK500. The most recently reported issues are listed below.
Gas tank leaks, car in moton in the street.
When the gas tank is full there is a very strong gas smell all around the automobile. The vehicle is parked with the ignition off. This should not be the case. The cel will come on with code p0456. A smoke test of the fuel filler neck showed there was a leak. Part w0133-2075480. This part is the same design as what is on the cls. This same fuel smell issue is on the e class and cls class and a warranty extension has been issued for an additional 15 years but nothing for the clk. This is a dangerous issue with heat and fuel and it should be addressed by mercedes na . After discussing with mercedes their stance is this is a normal ware item. I do not buy it.
Pulled into the driveway one evening and noticed a strong fuel smell. Using a flashlight, found a drip coming from under the passenger side rear of the car. The next morning a large gas stain was apparent under the car, but the drip had stopped. Started the car and the gas leak began again. Dropped the panels under the car and the leak is coming from the tank. The vehicle is now at a dealership and they claim the tank is cracked.
