My 2008 GL 320 CDI has lost power: It will run through all gears but won't rev, go beyond 60mph, and runs like my grandmother is driving. "Check Engine" is on, but nothing sounds or looks unusual on the engine.

Hello. Well I can tell you that you have most likely a turbo issue or a air inlet port shutoff motor issue since those are the top two reasons the diesels go into limp mode. The fact you have a check engine light on is good since it will tell us a code that will help narrow down the issue. Is there a auto zone or oriellys near you ? They can read the codes for no charge. Just don't take any of their repair suggestions lol. If you get me the code we can go further. I am here to help. Lou

What about dirty air mass meter/sensor, dirty air filter or fuel filter?
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 2 years ago

Very well could be. But not as likely. And I would not like to guess. It would save tons of time and money for you to just get the codes read and then I can give you exacts. :)
