I recently had a gas tank pressure sensor replaced on my 1997 e model mercedes. Upon inspection of the interior of the gas tank, it was discovered that the return lines inside the tank had become disconnected which could result in loss of tank pressure, leakage, and /or improper emission system sensor readouts. The tank has not been damaged due to mpact so the disconnected line appears to be a design or engineering defect. In addition, the improper functioning of the return line equipment within the gas tank has a major impact on gas mileage. The defective return lines require the replacement of the total gas tank as a repair measure at a cost of over $800. I have retained the defective tank. Please advise if you need any additional details.
The gas tank on my Mercedes Benz e420 collapsed. It looked like a giant stepped on it. Prior to the tank collapsing the "check engine" light came on and I had to have the fuel evaporation system repaired. I took the car to berberian european motors (a Mercedes Benz dealer) in stockton CA. For repair. This failure is supposed to be covered by my califorina emission control warranty. The Mercedes Benz factory rep. Said that they were not going to fix the problem under the warranty and I had to pay for all the repairs myself. My point in contacting you is that a gas tank that just crumpels up by itself seems to be a safety problem you should look into. The other question is, why is Mercedes Benz not intrested in taking care of the problem under the emission warranty?.
