Peugeot 308 eloys pump not working after fitting a new dpf

Take it to another garage who know more about diagnosing the fault codes and rectifying the faults than your present garage .

Should I be able to hear or feel the eloys pump working if I listen underneath, can't hear anything coming from it,
Thanks

Could check your fuses , Usually the ECU calculates the amount of diesel added. and then runs the pump for the appropriate time needed to pump the required amount of eloys fluid into the fuel tank.
