Mercedes-Benz says the E320 Bluetec is the cleanest diesel. We were told when we did the first warrantee work that it was strange for the turbo charger to fail at less than 60,000 miles. Many folks think of diesel engines as loud, sooty and crude, but today's high-tech diesels are clean, quiet and 20 percent to 40 percent more efficient than gasoline engines. I am starting to shop for it's replacement and it will be another Mercedes. You could say that because it is over 100,000 miles that we should figure things would go wrong with it.
Still looked beautiful when I let it go because I treated her as good as she treated me. Trading off for a Lexus or Infiniti. It was supposed to be replaced and also since there was a know issue with the manifold, they should have been replaced also. I did my research and treated it as an investment. Coil problems, drops cylinders, cracked intake manifold.
Unfortunately we are finding out that this is not the case. Only had 8 months with numerous repairs. Will miss the car but not the cost to maintain it. We thought buying a Mercedes was a step up from the cars we had purchased in the past. The car drove nicely, handled well and had plenty of room in the back seat for passengers. The car treated me very well and never left me on the side of the road.
They also emit less carbon monoxide and carbon dioxide. Because the manifolds were not replaced at that time, they caused the failure of not only themselves, but also the turbo charger again. This has been an amazing and beauiful car with a workhorse of an engine. It only had 83K miles on it but developed an oil leak that these cars are notorious for that was going to be very expensive to try and fix if it could have been fixed. Lots of cargo room in the back also. . Our Take on the 2007 Mercedes-Benz M-Class Mercedes-Benz has long been a proponent of diesel engines, and the current Bluetec is so good that its quiet performance and good fuel economy are sure to win over customers.
Because of this issue, we probably will be replacing this car soon. With the Bluetec technology, nitrogen oxide is reduced with two additional catalytic converters. Loved the car and literally got teary eyed when I traded it. One problem after the next. But now we are looking at replacing the same parts on the same car just 40,000 miles later. Instead of buying a car ever 3-4 years I wanted something that would take me at least 7 years for quality and performance and expense.
My problem was a known problem with this engine and it should have been a recall. Well, our problem with this issue is that when it was under warrantee guess what failed. . . .
