Year of Manufacture *: 2004 Engine Size and Code *: 2.0 CRTD ( Optional ) Scanner Used: Maxidas/Hannatech ( Optional) Fault Codes: P1181
After wasting time on incorrect code description with both scanners, I eventually got the description for P1181 as 'fuel pressure monitoring'. The car starts instantly, and pulls very well at low and high revs, small and large throttle openings. Then, without warning, car can cut out in first or second gear when pulling away from a junction. Unfortunately it is unpredictable and unrepeatable, but always in the same manner. Code P1181 is logged. Clearing the code, or turning the ignition off for several minutes, allows the car to be re-started. Fuel supply pressure, before and after the filter head, has been 2.4 bar when this has happened. The engine fires up when the pressure reaches 1.5 bar, and can go as high as 2.9 bar. The tank and pick ups are clean. Leak off showed one injector 50% higher than the others, which were even, so has been replaced with a new one. The other three are now 30% lower than the new one! Rail pressure and drv demand, on live data, are good, but pressure drops like a stone when the engine cuts out. I am now looking for words of wisdom, though silver bullets are also accepted Peter
