Service bulletins for the 2013 Audi A6
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.

| 01146320336302 | 2023-01-03. Service bulletin. ELECTRICAL SYSTEM. Because there are a number of different misfire faults (unrelated to ignition coil operation) that could cause the MIL to illuminate, proper Guided Fault Finding (GFF) misfire diagnosis must be followed before any ignition coils are replaced. |
| 01146220361693 | 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?. |
| 011460203391912 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. One of the vacuum actuators on intake runner bank 1 or bank 2 is defective. It is possible that the membrane on the vacuum actuator may tear. As a result, the intake manifold flaps do not function. |

| 01145620329002 | 2023-01-03. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:SOFTWARE. The fault listed can occur under certain driving conditions. It is caused by an incorrect software setting. Some driving scenarios (such as extended idling or heavy stop-and-go traffic) can cause a slight misinterpretation of the data, which causes the MIL to illuminate. |
| 01145120305808 | 2023-01-03. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. The remote key being used is transmitting incomplete immobilizer information to the vehicle, resulting in the condition. |
| 01140320332233 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. The programmed values for the misfiring recognition are not automatically reset by deleting the memory once. |
| 01139820339191 | 2023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. One of the vacuum actuators on intake runner bank 1 or bank 2 is defective. There may be slight power reduction at high RPMs. |
| 01139720305806 | 2023-01-03. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. The customer complains that the vehicle sporadically cannot be started. The remote key being used is transmitting incomplete immobilizer information to the vehicle; resulting in the condition. |
| 01139420305805 | 2023-01-03. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. The remote key being used is transmitting incomplete immobilizer information to the vehicle; resulting in the condition. |
| 01138920337681 | 2023-01-03. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. A cylinder misfire fault (DTC P0301 ? P0306) with DTC P130A is stored in the engine control module (ECM), J623 (address word 01). |
| 01138620336301 | 2023-01-03. Service bulletin. ELECTRICAL SYSTEM. Because there are a number of different misfire faults (unrelated to ignition coil operation) that could cause the MIL to illuminate, proper Guided Fault Finding (GFF) misfire diagnosis must be followed before any ignition coils are replaced. |
