1441203507362022-08-01. Service bulletin. ENGINE AND ENGINE COOLING. The NVLD pressure switch may erroneously detect a very small leak.
1440203383622022-08-01. 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.
1438203811322022-08-01. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Various parts have been replaced under warranty for the condition noted above, but no issues were identified with these parts. In an effort to gain information on the DTC code listed above, we are asking that you contact the Audi Technical Assistance Center (TAC) before replacing any parts. This will assist us in diagnosing any potential issues with the condition noted above.

1431203507332022-08-01. Service bulletin. ENGINE AND ENGINE COOLING; FUEL SYSTEM, GASOLINE. The NVLD pressure switch may erroneously detect a very small leak. New pressure sensors in production: ? For vehicles with a fuel tank pressure sensor, G400, and a fuel tank leak detection control module, J909, that are separate (two components): part numbers 8K0906253 and 8K0906253B supersede to 8K0906253D. ? For vehicles with a fuel tank pressure sensor, G400, and a fuel tank leak detection control module, J909, which are integrated (one component): part numbers 8K0906253A and 8K0906253C supersede to 8K0906253E.
1328203507322022-08-01. Service bulletin. FUEL SYSTEM, GASOLINE. After the engine is switched off, the fuel system creates a natural vacuum as the fuel in the fuel tank cools off.

1327203507312022-08-01. Service bulletin. ENGINE AND ENGINE COOLING. EVAP System Leak Detected NVLD (very small leak))
1453203901812022-08-01. 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.
1449203685212022-08-01. 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.
1453203812922022-08-01. 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.

1452203811922022-08-01. Service bulletin. BACK OVER PREVENTION. 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.
1451203811912022-08-01. 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.
