How To Catch Failed MAP Sensor Mercedes GL

In this video, we going to show, how to diagnose a failed/bad/faulty MAP sensor (Charge Air Pressure Sensor) on Mercedes. Some times it is called Boost Pressure Sensor...
Fault/error codes (using Star Diagnosis Xentry):
DTC 0105-002 Check component B5/1 ( Charge Pressure Sensor). The signal voltage is too low.
DTC 0105-08 Check Component B5/1 ( Charge Pressure Sensor). The atmospheric pressure between component B5/1 (Charge pressure sensor) and component N3/9 (CDI control unit) is implausible.
DTC 0105-01 Check component B5/1 (Charge pressure sensor). The signal voltage is too high.
DTC 0105-04 Check component B5/1 (Charge pressure sensor). CAN signal faulty
Car spec:
Mercedes GL X164 420 CDI

I've got same code and n3/26 rail pressure would this be the fuel rail pressure sensor as well or just down to boost pressure sensor
