I purchased a 2012 ML350 Bluetec about 2 months ago and it has about 65,000 miles. Last night I started it up and drove down the road, got up to about 35mph very slowly and then pushed the gas to speed up and...nothing. So I stopped, turned it off and back on then was good to go. Next time I started it up it did the same thing, it let me accelerate slowly but mashing the gas pedal does nothing but a restart seems to fix it. The check engine light is on now.

I had a guy at AutoZone read the codes and there were two, one said Turbocharger overboost condition confirmed, and the other said Exhaust Pressure Sensor A Circuit Range.

Has anyone had a similar problem? I'm taking it to the dealer in the a.m. but wanted to check on here first. Thanks for the help!

It's obviously going into the Limp Home Mode, which is a pretty sure sign that the dealer service department needs to be visited.

It ended up being an exhaust pressure sensor and $450 to fix.
