Peugeot 406 anti pollution fault

Car: Peugeot 406
Variant: hdi 90 rapier estate
Model Year: 2001
Categories: Electrics, ECU, Warnings & Lights
When I start my car the engine management light is on and the display reads Anti Pollution Fault. I went to a garage and they diagnosed the fault code as the fuel pressure sensor regulator on the diesel pump. I replaced this, but a month later, the same fault has returned. I have also replaced the primary pump inside the fuel tank. Any advice would be gratefully received.
