Service bulletins for the 2014 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.

| 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. |

| 01131320343591 | 2022-09-26. Service bulletin. ENGINE AND ENGINE COOLING; FUEL SYSTEM, DIESEL. 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. |

| 145320390181 | 2022-08-01. Service bulletin. ENGINE AND ENGINE COOLING; FUEL SYSTEM, GASOLINE. A small amount of dry or crusted coolant is seen on the coolant pump housing (Figure 1, Figure 2, and Figure 3). The coolant level warning is not on. A minor coolant leak is possible during the break-in phase of the coolant seal on the coolant pump. The dry coolant marks are normal. |
| 144920368521 | 2022-08-01. Service bulletin. ENGINE AND ENGINE COOLING. The cooling fans may operate for up to 10 minutes after the engine is turned off. This function is mapped to specific driving patterns and vehicle operating modes (for example, DPF regeneration). This is normal operation, and no parts should be replaced. |
| 145320381292 | 2022-08-01. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION. A check with the engine oil service dipstick T40178 is necessary, but the adjustment values for the dipstick are not available in the Elsa repair manual. Because of a system change, the adjustment values for the service dipstick T40178 were removed from the repair manual. |
| 145120381191 | 2022-08-01. Service bulletin. ENGINE AND ENGINE COOLING. The message ?Oil minimum warning, add one quart of oil? appears in the instrument cluster, but the oil level is above the minimum level (when measured with special tool T40178). ? There are no DTCs related to oil level stored in the ECM memory. The oil level sensor is defective. |
| 145020381291 | 2022-08-01. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION. A check with the engine oil service dipstick T40178 is necessary, but the adjustment values for the dipstick are not available in the Elsa repair manual.

Customer states excessive turbocharger resonance or intake air noises during acceleration. The concern can be reproduced at approximately 30% throttle loading and medium RPM. No intake leaks found. Production tolerances in intake hose can cause amplification of normal turbocharger noises. |
| A1722172060750_3 | 2022-04-05. Service bulletin. ENGINE AND ENGINE COOLING. This bulletin contains instructions for using the UV additive to find engine oil leaks. |
