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.

Bulletins, newest first
A1923362025303142023-04-06. Service bulletin. ENGINE AND ENGINE COOLING. This bulletin provides information on the discontinuation and mixing of Audi-approved engine coolants.
A0123412014753122023-03-06. Service bulletin. ENGINE AND ENGINE COOLING; FUEL SYSTEM, GASOLINE. This bulletin contains instructions for when to add gasoline additives for cleaning the injectors.
Edition922023-02-06. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM. Idenifying and mixing factory fill engine coolants
Edition1142023-02-06. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER. Wastegate linkage dissconnected
Edition832023-02-06. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM:IGNITION. 97 no start
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?.
0114602033919122023-01-03. 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.

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.
011398203391912023-01-03. 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.
011389203376812023-01-03. 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).
011378203337912023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. An oil filter that is too short is installed. The oil filter must be 155 mm.
011373203322312023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. Engine warning light on after engine replacement
011372203321112023-01-03. Service bulletin. ENGINE AND ENGINE COOLING; FUEL/PROPULSION SYSTEM. Technical Background: Under extreme driving conditions (e.g. long idle periods or extended stop and go traffic), high temperatures build up in the rail system and can lead to steam bubbles in the fuel. This causes temporary drops in fuel pressure, causing DTC P008700 (fuel rail pressure too low) to be stored. Freeze frame data will indicate those extreme driving conditions: coolant temperature is above 102? C. Production Solution: Software to optimize the cooling strategy to solve this issue is currently in development.
011342203337922023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. An oil filter that is too short is installed. The oil filter must be 155 (+/-1) mm long. If the oil filter is too short, the drain flap in the oil filter housing will not be completely closed and oil pressure will be lost.
0113342033919112023-01-03. 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.
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.
011316203391982023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. One of the vacuum actuators on intake runner bank 1 or bank 2 is defective.
011314203391972023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. One of the vacuum actuators on intake runner bank 1 or bank 2 is defective.
011311203391962023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. One of the vacuum actuators on intake runner bank 1 or bank 2 is defective.
011306203391952023-01-03. Service bulletin. ENGINE AND ENGINE COOLING. One of the vacuum actuators on intake runner bank 1 or bank 2 is defective.
