MIL ON, No Start, or Rough Running with DTCs P0087, P0088 or P0191 Stored in ECM Fault Memory (TDI ONLY) MIL ON, No Start, or Rough Running with one or more of the following DTCs Stored in ECM Fault Memory: DTC Description P0087 Fuel Rail/System Pressure - Too Low P0088 Fuel Rail/System Pressure - Too High P0191 Fuel Rail Pressure Sensor "A" Circuit Range/Performance Technical Background When diagnosing the condition above on a common rail diesel vehicle, if no root cause is found after checking all other components and all GFF diagnostic procedures have been performed, it may be necessary to check for metallic particles in the High Pressure Fuel Pump using the service section of this bulletin. If such an inspection is necessary, the following guidelines must be observed when removing the N290 Fuel Metering Valve. Production Solution No production change required.

Technical Bulletin Service Note: Removing the N290 Fuel Metering Valve to inspect for metallic particles should only be considered as a last step after all GFF diagnostic procedures have been performed. This includes testing supply pressure to the high pressure fuel pump (low pressure side), and checking for internal leakage from the injectors and the N276 Pressure Regulating Valve Note: Prior to removing the N290 Fuel Metering Valve, the area surrounding the valve (Figure 1) must be clean and dried with compressed air to remove ALL debris from the area. See Repair Manual Group 20 Fuel Supply, General Information, Clean Working Conditions in Elsa. If debris enters the fuel system, components may be damaged. Figure 1. Surrounding Area 1. Remove the N290 Fuel Metering Valve and inspect the valve and valve bore for the presence of metallic particles (see Figure 2). Figure 2.

Technical Bulletin 2. If metallic particles are found on the N290 Fuel Metering Valve or in the valve bore, proceed to step 5. If no metallic particles are found on the N290 Fuel Metering Valve or in the valve bore, do not replace the high pressure fuel pump. Reinstall the valve and continue with the diagnosis. Note: To prevent fuel system damage, ensure that the N290 Fuel Metering Valve is free of any contaminates before reinstalling. Prior to reinstallation of the N290 Fuel Metering Valve, ensure that both O-rings are not damaged. If they are damaged, the high pressure fuel pump must be replaced. To prevent damaging the O-rings when reinstalling the N290 Fuel Metering Valve, lubricate the O-rings with diesel fuel (see Figure 3). Figure 3. N290 Fuel Metering Valve O-rings 3. Install the N290 Fuel Metering Valve into the valve bore using light pressure. 4. Install and hand tighten both M5 fasteners, ensuring that the threads are clean and dry. Pre-tighten to 2 Nm, then to 6.5 – 7 Nm. Page 3 of 5 © 2014 Volkswagen Group of America, Inc. All rights reserved.

Technical Bulletin Note: Using a paint marker or equivalent, mark the top of the N290 Fuel Metering Valve with a white dot as shown in figure 4. Tip: Be sure to include the 7 digit technical bulletin number in the repair order comments. Figure 4. White dot on N290 Fuel Metering Valve 5. If metallic particles are found on the N290 Fuel Metering Valve or in the valve bore, open a VTA ticket and contact the Volkswagen Technician Helpline before continuing with the repair. Clear pictures showing the metallic particles in the N290 Fuel Metering Valve and bore, as well as the GFF diagnostic log are required to continue with diagnosis and/or release of the High Pressure Fuel Pump. Reference the pictures below for examples. (see Figures 5 & 6). Tip: Prior to calling the Technician Helpline, have the pictures and the GFF log attached to the VTA ticket. This will help to ensure a timely repair. Figure 5. N290 Fuel Metering Valve with Metal Particles Page 4 of 5 © 2014 Volkswagen Group of America, Inc. All rights reserved.

Technical Bulletin Note: If a fuel system replacement is necessary, ensure that the fuel injector return line is properly seated and sealed once installed. Inspect for seepage at the fuel injector return line connector after the test drive. If seepage is found, the condition must be corrected. Figure 6. Valve Bore with Metal Particles Tip: Be sure to include the 7 digit technical bulletin number in the repair order comments. All TDI Clean Diesel High Pressure Fuel Pumps that have been replaced in conjunction with this Technical Bulletin will be requested for return. These replacement parts will be reviewed to verify the presence of metallic particles on the N290 Metering Valve and within the bore to ensure that the submitted part matches the information submitted with the VTA.
