its making really loud pumping sound,doesnt seem to be producing air as wont move from standard height and the pump itself is very very hot to the point you cant really touch it,fault code was reset and it hasnt come back but it still wont move , ive ordered new rear bags as there needing done i think im just going to replace the pump for the dunlop one from island 4x4 for 159.99 then i know its right what do you guys think was told it wasnt a genuine pump so is it worth it
