Code 547 is used by 15 different Scania systems. Choose the control unit shown in your diagnostic tool:

EMS Engine Management System Post injection ontime too long, cylinder 3. The error is detected when the post injection ontime, for either post1 or post2, has been consequtively too long for a period of time. Read explanation → VDT Output signal Short circuit to battery on output for control unit E754. Read explanation → COO Coordinator Manual activation of retarder The voltage in the circuit for the retarder lever or for the auxiliary brake lever has been below the permitted level. Read explanation → MBS Brown CAN bus, no communication The MBS control unit fails to detect communication on the brown CAN bus within the set time period. Read explanation → ELC Electronically controlled air suspension Voltage supply for solenoid valve. The voltage on the output to the solenoid valve has been too high.
