Technical Service Bulletin Technical Background Contaminated or incorrect fuel can cause performance, drivability, and/or fuel delivery problems. Additional component replacement may be necessary to ensure that no contamination or debris remains after repair. Reasons for fuel contamination can include: water ingress in the fuel station’s holding tanks, errors made in fuel transport, or incorrect fuel has been dispensed into the vehicle. Production Solution Not applicable. Service Note: Failure to follow these directions may result in immediate damage to any replacement parts due to fuel system contamination. Inspect the fuel filter housing: If there is any indication of fuel contamination, metal shavings/debris, or rust inside the fuel filter housing (Figures 1 and 2), open a ticket with the Technical Assistance Center (TAC) before attempting any repair. Figure 1. Example of metal shavings and debris on top of fuel filter. Some shavings can be picked up with a magnet. © 2013 Audi of America, Inc. Page 2 of 5 All rights reserved.

Technical Service Bulletin Figure 2. Example of rust in fuel system caused by water contamination. If the fuel filter is not a serviceable unit (example: MY 2011+ Q7 TDI), then inspection must be performed at the fuel metering valve N290: Note: Exercise caution when removing the N290. Any dirt/contamination entering the pump may cause damage. 1. Before removing the N290, carefully clean the surrounding area. 2. If there is no metallic debris found on the N290 or within its housing, refit the N290 valve immediately. Make sure both O rings are undamaged. If there is any damage to either O ring, the high pressure fuel pump must be replaced. 3. When fitting the N290, slightly wet the lower O ring with diesel fuel or oil. 4. Push in the N290 using only light pressure. 5. Tighten both M5 bolts hand tight – do not lubricate the thread. 6. Pre-tighten with 2 Nm, then 6.5-7 Nm. © 2013 Audi of America, Inc.
