Service bulletins for the 2011 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.

962 on file from NHTSA, as of 2026-10-19.

011462203616932023-01-03. 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?.

011403203322332023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. The programmed values for the misfiring recognition are not automatically reset by deleting the memory once.
011400202629942023-01-03. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ELECTRICAL SYSTEM. An incorrect software setting causes the DTC to be stored.
011390203376712023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. 01 MIL on (DTC P1196/P1197/P0135, heater circuit fault lambda sensor) - Repair Authorization
011383203300112023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction.
011373203322312023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. Engine warning light on after engine replacement
011366203145832023-01-03. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV). Under extreme driving conditions, such as a driving profile of mainly short distance (stop and go) driving high crankcase pressure can lead to the above described DTC codes.
011349203545422023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction. The ODIS tester can identify the state of the restriction, and will request that the system is cleaned in order to prevent the MIL from illuminating.
011348203300152023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction.
011345203145842023-01-03. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV). Under extreme driving conditions (such short-distance, stop-and-go driving), high crankcase pressure can cause the DTCs to appear.
011337203300142023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction.
011335203545412023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. During reset of the service reminder, the following message appears on the ODIS tester: ?Secondary air injection system - checking secondary air mass?. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction. The ODIS tester can identify the state of the restriction, and will request that the system is cleaned in order to prevent the MIL from illuminating.
011329203322322023-01-03. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM). The programmed values for the misfiring recognition are not automatically reset by deleting the memory once.
011309201475382023-01-03. 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.
011301203300122023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. Under certain driving conditions, the secondary air ports in the cylinder head can accumulate carbon over time, causing a restriction.
011258203145812023-01-03. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV). Under extreme driving conditions, such as a driving profile of mainly short distance (stop and go) driving high crankcase pressure can lead to the above described DTC codes. By changing the crankcase pressure valve to a lower operating pressure this condition can be improved and eliminate the mentioned possible DTC codes. Along with the crankcase pressure being lowered, a new ECM software level is required to compensate for new crankcase pressure.
001470203920612023-01-03. 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.
