DTC “ P014800 Fuel Delivery Error” stored in the ECU. “ Misfire ” DTC stored in the ECU. Technical background There may be multiple DTC’s and symptoms present due to fuel pressure regulation or fuel supply issues, use the information contained within the “Measure” section to determine the correct analysis and repair procedure. Production change Not applicable. Measure Check Engine Lamp Illumination And DTC “P0310B00” For vehicles that have only the symptoms “Check Engine Lamp Illumination”, DTC “P031B00” and an “Adaption of Fuel Pump (FP)” figure of minus 100 to minus 200 kPa – figure 1 - the Fuel Delivery Module within the fuel tank should be replaced – figure 2 – refer to Repair Group 20 Fuel supply, gas operation / 4.0L V8 TSI / Fuel pump, fuel level sensors, and jet pump (RH) – To remove and fit. To check the “ Adaption of Fuel Pump (FP) ” figure within the fault memory, refer to ECU “ 01 – Engine Control Module 1” From “ Extended ambient conditions” note the value of the “Adaption of Fuel Pump (FP)” – figure 1. Figure 1 Figure 2 Check Engine Lamp Illumination, Engine Running Concerns, Fuel System and Misfire DTC’s With symptoms of “Check Engine Lamp Illumination”, “Poor Engine Running” accompanied with one or more of the following DTC’s: • “ P310B00 Low Fuel Pressure Regulation” • “ P014800 Fuel Deliver Error” • “ Misfire ” DTC’s Check “Low fuel pressure, specified value” and “Fuel low pressure, actual value” within the fault memory, refer to ECU “01 – Engine Control Module 1” - From “ Extended ambient conditions” note the values of the “Low fuel pressure, specified value” and “Fuel low pressure, actual value ” – figure 3. Figure 3 Next, raise a DISS query. • Note the “Low fuel pressure, specified value” and “Fuel low pressure, actual value” on the DISS query. • Attach a diagnostic log and report if the fault is reproducible. The following checks may also be requested via the DISS query: • Low pressure fuel system – Fuel pressure check using ODIS measured values when the vehicle is starting or idling – this should normally be 400 – 800 kPa. • If possible, check the fuel system pressure at the fuel tank outlet with a pressure gauge, this should be the same as the figure measured with ODIS or approximately 100 kPa lower if the gauge is relative to atmospheric pressure. • After switching the engine off the pressure within the fuel system should remain at 400 kPa or above for at least ten minutes. If the fuel system pressure is not as expected it may be necessary to check the fuel tank internally – check for disconnected or punctured fuel lines. • Check the fuel level within the fuel tank, check the fuel pump electronic control unit electrical earth point condition and check for debris within the fuel tank. • If removed, the fuel pump and fuel pump control module may be required for further analysis.
