Service bulletins for the 2014 Audi A8
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| 01146120352352 | 2023-01-03. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING. The fuel metering valve of the high-pressure fuel pump is controlled by a specific on/off ratio. If there is a low system voltage, the on/off ratio may not be enough to keep the fuel metering valve constant in all areas. In such a situation, the fuel metering valve is deactivated and the high-pressure fuel pump switches to full supply mode. Because the increased rail pressure does not match the respective driving situation, the DTC appears. |

| 01145920361692 | 2023-01-03. Service bulletin. FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING. 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?. |

| 01140420353684 | 2023-01-03. Service bulletin. ELECTRICAL SYSTEM. Due to a production issue for the level sensor, the ECM cannot correctly read the reductant (AdBlue) fluid level. |
| 01139620233604 | 2023-01-03. Service bulletin. ELECTRICAL SYSTEM; FUEL/PROPULSION SYSTEM. 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. |
| 01133620352351 | 2023-01-03. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING. fuel rail pressure too high; noises from engine compartment |
| 01133220353681 | 2023-01-03. Service bulletin. FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM). Due to a production issue for the level sensor, the ECM cannot correctly read the Reductant (AdBlue) fluid level. |
| 01132820332243 | 2023-01-03. Service bulletin. FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. If a model year 2014 Q5 TDI, A6 TDI, A7 TDI, or A8L TDI clean diesel (engine code CPNA or CPNB) requires diagnosis or repair of the engine, diesel fuel delivery, exhaust after-treatment (SCR/AdBlue and emissions) systems, or transmission, a Repair Authorization is necessary prior to repair. |
| 01131020332242 | 2023-01-03. Service bulletin. FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL. If a model year 2014 Audi Q5 TDI, A6 TDI, A7 TDI, or A8L TDI clean diesel (engine code CPNA or CPNB) requires diagnosis or repair of the engine, diesel fuel delivery, exhaust after-treatment (SCR/AdBlue and emissions) systems, or transmission, a Repair Authorization is necessary prior to repair. |
| 01130920147538 | 2023-01-03. Service bulletin. FUEL SYSTEM, GASOLINE. The use of contaminated gasoline or gasoline with a low content of deposit control additives may result in one or more conditions. |
| 00147020392061 | 2023-01-03. Service bulletin. EQUIPMENT:ELECTRICAL:INFOTAINMENT. High quality media files (video and sound) are now integrated into technical service bulletins on a case-by-case basis. Media files can now be viewed on any smartphone or tablet. |
| 00146620379491 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM). A DTC with the description ?Invalid Data Record? is stored after an ECU has been replaced or updated. |
| 001465201173210 | 2023-01-03. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. This Technical Service Bulletin (TSB) details the general process for carrying out a Software Version Management (SVM) software update for any TSB or Update. |
| 00146420355812 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. Although the correct amount of oil was added to the engine during an oil change service, a check of the oil level shows that the oil level is not okay. |
| 00146320335762 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. Although the correct amount of oil was added to the engine during an oil change service, a check of the oil level shows that the oil level is not okay. When an unapproved aftermarket speed-filling device is used to add oil to the engine, the increased oil flow rate may force oil into the intake manifold or combustion chamber, creating the potential for engine damage. |
| 00145920297372 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. When oil is drained through the drain plug, the oil might spill on components around the oil pan area. If it is not properly cleaned up, this spilled oil could drip after the procedure is complete, causing unnecessary customer complaints. |
| 00134920335761 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. Although the correct amount of oil was added to the engine during an oil change service, a check of the oil level shows that the oil level is not okay. |
