Service bulletins for the 2012 Audi Q7
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.

| 01136620314583 | 2023-01-03. 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. |
|---|---|
| 01134920354542 | 2023-01-03. 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. |
| 01134820330015 | 2023-01-03. 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. |
| 01133720330014 | 2023-01-03. 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. |
| 01133520354541 | 2023-01-03. 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. |
| 01131320343591 | 2023-01-03. Service bulletin. FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. In vehicles produced during a certain period, the AdBlue filter seal within the level sensor module may have been damaged during the assembly process. This damaged seal can allow unfiltered AdBlue to be sucked into the delivery system, subsequently damaging the pressure sensor and reducing agent pump V437. |
| 01130120330012 | 2023-01-03. 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. |
| 01125820314581 | 2023-01-03. 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. |
| 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. |
| 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. |
| 37139820257543 | 2022-11-21. Service bulletin. UNKNOWN OR OTHER; ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM):SOFTWARE; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE. Shift quality and operational concerns |
| 01146620306652 | 2022-10-31. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. The quality of the auxiliary exhaust gas recirculation (EGR) cooler modules manufactured within a certain timeframe may be inadequate. The vacuum actuator diaphragm may have leaks. A faulty auxiliary EGR cooler will trigger a P310E fault. Faulty operation of the auxiliary EGR cooler can also trigger the P040B fault, but there is no issue with the temperature sensor. |
| 01138320330011 | 2022-10-31. 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. |
| 01136620314583 | 2022-10-31. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV).

| 00134920335761 | 2022-10-31. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION. 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. |
| 01146620306652 | 2022-09-26. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. The quality of the auxiliary exhaust gas recirculation (EGR) cooler modules manufactured within a certain timeframe may be inadequate. The vacuum actuator diaphragm may have leaks. A faulty auxiliary EGR cooler will trigger a P310E fault. Faulty operation of the auxiliary EGR cooler can also trigger the P040B fault, but there is no issue with the temperature sensor. |

After recognizing that the boost pressure is too low or too high, the engine control module switches to emergency operation and the engine performance is reduced via the injected fuel quantity (?limp mode?). |
