Hi I've been suffering a few problems with my dturbo hdi, it would cut out under hard acceleration. Error code p0230 primary fuel circuit fault. I removed the lift pump and cleaned it out, problem still the same. Next port of call changed fuel pressure regulator (on the side of hp pump) with a used item from an r70 2.2hdi pump. Car ran fine for a day, come to the car this morning, car is underpowered will only rev to 2400rpm and will run on when switched off. My question is should the regulator move by hand. Is my used item faulty or hp pump fooked. Any help would be appreciated. Thanks Tom
