Well done guys. I have a 2011 Mercedes GL, 3.5 OHM 642 engine. I started to reset to emergency mode, first once, then more often. I called a lot of people, they said different things.
I turned to the guys, explained, did the turbine prevention and repair of the servo with a wear-resistant mechanism as presented to me. They gave recommendations (to give the car a tail) to pay attention to the exhaust manifolds (they collapse over time) and that's it. The price turned out to be lower than the others. The error disappeared, later I reset it on the computer. I don't fall into an accident anymore.
Thank you very much.
Mercedes 211 3.0 diesel, a boost error lit up and the turbine turned off. I turned to the TurboDoctor, took it off and brought the turbine. Thanks to the guys, well done, we made a diagnosis of the servo and the turbine itself. Verdict: Servo repair-replacement of gears (there was wear, which is why this problem occurred) and replacement of bearings and turbine blades.
They took it not expensive, compared to other offices where I called to clarify (they loaded something heavily on the move).
They said that they put spare parts in the servo of their own design(almost eternal) let's wait and see.
The problem is gone, I've been riding for 3 months.
I am writing now and sharing my impressions.
In general, I am satisfied.
Thank you very much! I recommend it!
