We have a 2010 Mercedes Sprinter 2500 with 96k miles on its V6 turbo diesel engine. The short story is after installing a new turbo the shop said my engine was no good because there was a spun bearing. I originally brought it in for a fan belt replacement and now waiting for over two months to get this news. First it was the turbo, then three weeks of waiting I was told about the bearing. There's a lot that he did that doesn't make sense or add up. Hard to believe a MB just all of a sudden destroys it's self. I was told that it was most likely caused by over boost because the turbo wasn't properly programmed in.
I think I might have to go to court on this one. $20k for a new engine.
Like above mentioned, and with cars like with whatever else you need to remember that when something goes out it spits a bits of metal. Verry little particles but still. So when you put new turbo cause old died its better to put rebuild turbo than new. New might work TOO good and put too much pressure on engine parts. It might be wrong programing or just worn out a little engine. Thats why Scotty says to buy naturally aspirated engines rather then turbo ones. Remember that its not just old oil that destroys engine but MOSTLY particles in that oil or lack of additives in oil, additives wear out over time or rather loose the shape cause of constant work.
that's the downside of MBs. They are so complex that few people know how to work on it properly.
