Update fuel system control unit (FSCU) software
This is to notify you of the upcoming Service Campaign to update the fuel system control unit (FSCU) software on approximately 48,913 MY16-20 Mercedes-Benz
Metris vans. All affected VINs will be flagged as “OPEN” in VMI.
Issue
MBAG has determined that the electric fuel pump on certain Metris vehicles may not engage due to a signal interruption after starting the engine. In this case, the engine would stop again after a short drive at slow speeds. If no residual pressure remains in the system, the engine will not start. After cycling the ignition, the engine restarts and the vehicle can continue driving.
What We’re Doing
MBUSA is conducting a service campaign. An authorized Mercedes-Benz Metris dealer will update the fuel system control unit (FSCU) software.
