A2323572040752112023-04-06. Service bulletin. This bulletin provides instructions for when the MIL is on, and the vehicle either runs roughly or does not start in the presence of one or more of the following DTCs: P008700, P008800, P019100
A011379 2023360-2017-11-17. Service bulletin. Supersedes Technical Service Bulletin Group 01 number 11-18 dated January 25, 2011. MIL on. DTC P0087 (Rail fuel pressure too low) or DTC P0088 (Rail fuel pressure too high) stored in the memory of the engine control module (ECM), J623 (01). Excess rattling ("diesel clatter") coming from engine. No start or hard starting condition. Loss of power while driving due to fuel system contamination. Contaminated fuel found in fuel system. Rust or metal debris found in fuel system. Contaminated or incorrect fuel can cause performance, drivability, and/or fuel delivery problems. Rust or metallic debris found in the fuel system indicates a major component failure. 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 gas station?s holding tanks, errors made in fuel transport, and incorrect fuel being dispensed into the vehicle via the customer or service station (full service) employees.
A011459 2036169-2017-11-08. Service bulletin. Supersedes Technical Service Bulletin Group 01 number 14-55 dated January 8, 2014. The MIL is on. DTC P0087 may be stored in the ECM. Drivability concerns such as hard starting/no starting are present. Outside temperature is sub-freezing. In tank, fuel pump may be making a straining noise.
A011455 2036169-2017-11-08. Service bulletin. The MIL is on. DTC P0087 may be stored in the ECM. Drivability concerns such as hard starting/no starting are present. Outside temperature is sub-freezing. In tank, fuel pump may be making a straining noise. Diesel fuel requires additive blending or ?winterization? to be useable at low temperatures. At temperatures below 20° F (-7° C), No. 2 Diesel with insufficient winterization blending may lose its fluidity due to wax separation. This may clog the fuel filter or in-tank filter, preventing the engine from operating properly. No. 2 Diesel is blended by refineries to various levels of winterization (minimum useable temperature) based on month, geographical location, and the 10th percentile minimum ambient air temperature for the given region. Although rare, during sudden periods of extreme low temperatures (record lows), fuel stations may not be adequately prepared with No. 2 Diesel fuel with sufficient winterization to resist wax formation or ?gelling?.
TSB-01-10-082011-01-10. Service bulletin. AUDI: MIL ON; NO START OR ROUGH RUNNING (DTC P0087-RAIL FUEL PRESSURE TOO LOW). CONTAMINATED OR INCORRECT FUEL CAN CAUSE PERFORMANCE, DRIVABILITY, AND/OR FUEL DELIVERY PROBLEMS. RUST OR METALLIC DEBRIS FOUND IN THE FUEL SYSTEM INDICATES A MAJOR COMPONENT FAILURE. *PE UPDATED ON 6/14/2011. *KB
TSB-24-09-282010-08-09. Service bulletin.
