1225203160712022-08-01. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING. To ensure mobility, a small amount of fuel is still available when a fuel range of zero miles is initially displayed. Additionally, the fuel range is calculated based on the most recent driving style. Therefore, the actual amount of fuel remaining may vary when a fuel range of zero is initially displayed.
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.
1346203349152022-08-01. Service bulletin. FUEL SYSTEM, GASOLINE. The leak can be traced to the connection of the water pump and the hose leading to the heater core (Figure 1). The seal ring is not the cause of the leak.
1344203349142022-08-01. Service bulletin. FUEL SYSTEM, GASOLINE. The leak can be traced to the connection of the water pump and the hose leading to the heater core (Figure 1). The seal ring is not the cause of the leak.
1342203349132022-08-01. Service bulletin. FUEL SYSTEM, GASOLINE. The leak can be traced to the connection of the water pump and the hose leading to the heater core (Figure 1). The seal ring is not the cause of the leak.

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. Because of a system change, the adjustment values for the service dipstick T40178 were removed from the repair manual.
1450203812912022-08-01. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION.

1449202844022022-08-01. Service bulletin. BACK OVER PREVENTION:DISPLAY FUNCTION. The customer complains of one or more of the following issues: ? When the vehicle is completely refueled, the vehicle range (?distance to empty?) that is displayed is different than the vehicle range that was displayed the last time the vehicle was completely refueled. ? The displayed vehicle range drops inconsistently. ? After the vehicle is refueled, the displayed vehicle range does not change for a long period of time. ? When the vehicle is driven on hilly roads for a long period of time, the displayed vehicle range suddenly changes by a significant amount. ? There are no DTCs related to fuel senders stored in the instrument cluster control module, J285 (address word 17). This condition does not involve or affect the accuracy of the fuel level indicator, but only the estimated distance to empty display on the on-board computer.
13462030197122022-08-01. Service bulletin. EQUIPMENT. In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically, engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. Refer to the Owner?s Manual for specific break-in procedures.
13452030197112022-08-01. Service bulletin. SERVICE BRAKES; EQUIPMENT. In order to provide effective lubrication and cooling of internal engine components, all internal combustion engines consume a certain amount of engine oil. Oil consumption varies from engine to engine and may change significantly over the life of the engine. Typically, engines with specified break-in periods consume more oil during the break-in period, and the oil consumption will stabilize after the break-in period. Refer to the Owner?s Manual for specific break-in procedures. Under normal conditions, the rate of oil consumption depends on the quality and viscosity of the oil, the RPM at which the engine is operated, the ambient temperature, and road conditions. Additional factors are the amount of oil dilution from water condensation or fuel residue, and the oxidation level of the oil. Under certain driving conditions, internal engine pressure conditions in the 3.0 TFSI engine can negatively influence the rate of oil consumption. This can occur while the vehicle is operated in city driving conditions, for example: stop and go traffic with extended idle periods.
