Hi guys. I've got a customers 54 plate V50 T5 in at work with a fault code 2900 Fuel pressure faulty signal. I'll admit I don't have much to do with later T5's. My first thought was faulty fuel pressure sensor, as luck would have it I had a spare which I swapped in but getting the same fault. I can clear the fault and monitor live readings and the fuel pressure stays at 4 bar (drops to 3.98 but can't see that being a problem) and the duty cycle increases to 57% when the revs are increased. I don't have to drive it it will re-log the fault code when stationary. I notice no blips in the reported fuel pressure. Anyone know if the duty cycle is too high possibly indicating a weak pump ? Anyone had any experience regarding this fault ?. No issues noted when driven.
Thanks in advance
