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.

| 01145920361692 | 2022-09-26. Service bulletin. FUEL SYSTEM, GASOLINE; FUEL SYSTEM, DIESEL. 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?. |

| 01139620233604 | 2022-09-26. Service bulletin. FUEL SYSTEM, GASOLINE. Contaminated or incorrect fuel can cause performance, drivability, and/or fuel delivery problems. Additional component replacement may be necessary to ensure that no contamination or debris remains after repair. Reasons for fuel contamination can include: water ingress in the fuel station?s holding tanks, errors made in fuel transport, or incorrect fuel has been dispensed into the vehicle. |
| 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. |
| 01130920147538 | 2022-09-26. 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. |
| 144220355912 | 2022-08-01. Service bulletin. FUEL SYSTEM, GASOLINE. Normal fuel system pulsation can cause slight vibrations in the pressure regulator on the flange located on the right side of the fuel tank. This pulsation also causes the long, curved fuel lines (Figure 1) to vibrate and make a jarring noise in the tank. |
| 144020338362 | 2022-08-01. Service bulletin. FUEL SYSTEM, DIESEL. Beginning with MY2009, the filler necks of various TDI clean diesel vehicles were equipped with a misfueling guard (Figure 1). The guard minimizes the likelihood that fuel other than ultra-low sulfur diesel will be put into the vehicle. The misfueling guard is designed to remain in a locked position when a nozzle with a diameter typically suited for non-diesel fuels (approximately 13/16?, or 20.6mm) is inserted, to prevent further insertion of the nozzle into the filler neck. A nozzle with a larger diameter typically suited for diesel fuel (approximately 15/16?, or 23.8mm) will unlock the misfueling guard when inserted, allowing the nozzle to be further inserted into the filler neck. |
| 143020355911 | 2022-08-01. Service bulletin. FUEL SYSTEM, GASOLINE. Customer reports hearing noises from the rear of vehicle or from fuel tank area. Normal fuel system pulsation can cause slight vibrations in the pressure regulator on the flange located on the right side of the fuel tank. This pulsation also causes the long, curved fuel lines (Figure 1) to vibrate and make a jarring noise in the tank. |
| 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. |
| 147520366682 | 2022-08-01. Service bulletin. STEERING; FUEL SYSTEM, DIESEL; FUEL SYSTEM, GASOLINE; SERVICE BRAKES. When diagnosing a MIL on, no-start, or rough running concern on a common rail diesel vehicle, and no root cause is found after checking all other components and following all GFF diagnostic procedures, it may be necessary to check for metallic particles in the High Pressure Fuel Pump. |
| 15 37 2040752 5 | 2022-05-31. Service bulletin. ENGINE; FUEL SYSTEM, GASOLINE. Metallic particles in the high pressure fuel pump may cause the condition. Vehicle either runs roughly or does not start. |
| 26 14 24 2038295 | 2022-05-02. Service bulletin. FUEL SYSTEM, GASOLINE. The reducing agent transfer pump V436 may be faulty. The vehicle cannot pump AdBlue from the passive tank to the active tank. Cars in hot weather regions are more prone to this issue. |

| A261526 2038295- | 2018-03-13. Service bulletin. FUEL SYSTEM, DIESEL. Supersedes Technical Service Bulletin Group 26 number 14-24 dated September 16, 2014. There are ?Refill AdBlue? warnings in the cluster. The warnings appear approximately 1,500 - 2,500 miles after the last top-off. When the AdBlue tank is refilled, the vehicle will only accept approximately 1 - 2 gallons of reductant. When checked manually, the active tank is 50% full or less and the passive tank is full. There are no reductant system fault codes stored. If any reductant system fault codes are stored, this TSB does not apply. The reducing agent transfer pump V436 may be faulty. The vehicle cannot pump AdBlue from the passive tank to the active tank. Cars in hot weather regions are more prone to this issue. |
