Possible fault causes

• Faults that lead to limp-home mode (See)
• DME (DFI) control unit software error
  • Re-programming (See)

INFORMATION 

When a serious fault is detected in the engine control system (control unit or parts such as the throttle valve, etc.), the control unit switches to a limp-home program and simultaneously stores a corresponding fault. The Reduced engine power  warning message is displayed in the instrument cluster.

• This fault might not be detected again immediately after a restart.
• Fault P0607 is therefore stored as well, and the control unit already switches to the limp-home program during the restart.

• If one or more other faults are entered in addition to fault P0607:
  • first correct the other faults,
  • then erase the fault memory and meet the diagnostic conditions.
• If only fault P0607 is stored, there is an error in the software.
  • Re-programming DME (DFI) control unit
