Eberspacher X2 pump


Recommended Posts

Hi Joergen and welcome to the forum,


First question, are you certain it is the pump that has failed? It is not a 'normal' pump with a 12 volt feed but a 'Dosing' pump which receives a 'pulse' of electricity whenever the Espar requires fuel.


I believe you can test the pump by momentarily 'tapping' the live wire on a 12 volt supply and listening for the pump clicking. If you connect it to a permanent 12 volt supply nothing will happen.
