This video will show you how to check the turbo boost pressure on your Mercedes (we are using a C Class in this video, but it is the same for any Mercedes like A Class, B Class, E Class, S Class, G Class and everything else)
You can pick up the MB V1.0 tool as shown in this video here: https://www.diagnostic-world.com/page...
In this Mercedes C Class, it allowed us to see engine speed (rpm), intake air temperature, boost pressure, exhaust back pressure, on/off ratio charge pressure positioner, boost air temperature, atmospheric pressure.
