This is a NEW, GENUINE Citroen C5 MK I (2001-2005) Hydraulic Suspension Pump. The pump can also be used on C5 MK II and MK III (X7) but the ECU will either need coding (which I cannot help with) or you will need to swap over the ECU from your old unit.

Number on pump 9646052280/B, number on ECU 9643373280 H1 Type. Citroen Part Number 527745. Please look at pictures carefully if the numbers are not the same on your old unit.
