Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you tell me if the engine is lacking power or if there are any strange noises coming from the engine?
Thank you. Does you scan tool read the boost sensor data?
Some generic scan tools will read it. You need to see what the boost pressure sensor is doing when this occurs. If it drops to nothing then the sensor may be bad. If not then the turbo is the next most common failure.
Re-manufactured turbos are about a 50/50 shot of them working well and lasting. As for the sensor, yes it can cause this if it is reading incorrectly.
