The diagnosis MB from this error:

Code:
 0105-001 Check the pressure transducer B5 / 1. The boost pressure is too high. 

Check (instruction from stardiagnosis machine): 
The atmospheric pressure and the suction pressure (with ignition ON and engine off) should not differ by more than 30 mbar (30hPa, 3kPa). 
I checked the value and have a maximum deviation of 1kPa. 

solution: 
Check for loose contact on the cables between the engine control unit and the sensor.

It seems to me that there are not ...
This sensor can be cleaned? How?
I have verified that there are traces of oil aspiration, they may have damaged it?

Do you think the problem is the map or something other?
