| Diesel Fuel System problems |
Vehicle has strong gasoline odor in the passenger cabin. Appears to be similar to other complaint reports for same vehicle type (e type). No gas leaking below vehicle. Concerned that fire might result from spark in the cabin or near the car. Shouldn't this be a recall issue for public safety?.
I took my 2007 Mercedes Benz blutech to the dealer for the once a year "b" service. While they were doing the service, they noticed diesel fuel leaking behind the left rear tire. I had them perform an inspection for $135 and they determined that fuel was leaking out of the left fuel level sender area with no visual damage. They recommended replacing left tank seal and inspecting tank and sensor for cracks for $368. Before having the work performed , I went on the internet and found others having the same problem with their mercedes with NHTSA action #pe12001. We had no fuel smell or any indications there was a leak. I feel this is a serious defect and Mercedes Benz should recall these vehicles before someone gets killed.
I noticed fuel stains on bottom of fuel tank and smell of diesel in my garage especially after fill up. I told the dealer when I had the car in for service. They said I had a fuel leak and the fuel tank would have to be removed to find the source. They said the problem could be the tank, sending unit, or seals. . . . All very expensive to diagnose/ repair. I met with the service mgr to seek an out of warranty coverage and got nothing. I called mercedes corporate customer service. They declined to cover any out of warranty repair costs. I removed the rear seat and found fuel puddling around the sending unit (in the tank) on the driver?s side. It is unconscionable that there are fuel leaks in a high line expensive car like this. Mercedes customers should rightfully expect a leak free fuel tank for the life of the car. It is shameful that mercedes doesn't own up to it and issue a recall notice and fix this before someone is killed.
2 highway stallings: 1) Dec. 1. 2009 traveling on I-95 south at 70mph, check engine light on, car suddenly stalled, managed to pull to shoulder. Car towed to benz dealer 90 miles away. They changed a new fuel pump in charleston, SC. Continued driving on 2) Dec. 3,2009, after 400+ miles on I-95 south at 70mph, check engine light on, car suddenly stalled again, managed to pull to shoulder. Car towed to benz dealer in melbourne, florida. They changed another fuel pump and filter. Now I am driving with my finger crossed.
At 2 separate times the high pressure diesel injection system failed and dumped raw diesel all over. On the last event it sprayed against the exhaust headers and created a lot of smoke.
