Fast check before you buy an S Tronic car
There are few quick steps you can follow to check if a car with S Tronic gearbox is operating correctly. First, make sure that the gearbox oil is over 80 C. Start the engine and start driving slightly pressing the accelerator pedal.
Drive 140 meters and stop gently. If everything is working smoothly with no hard shifting and jolting the gearbox should be OK.
Always check how the vehicle is moving in reverse gear with the oil temperature of the box above 80 C. There must be no jolt, hard shifting or loss of torque. It is convenient to make those tests on a slope with hot gearbox.
Filters and Oil Change
The S Tronic gearbox has two different filters – exchangeable paper filter and an in-line oil filter (in steel box). The in-line filter must be removed when the ATF is very dirty or the gearbox is being renewed. The changeable filter must be replaced each time the ATF is changed or the gearbox is repaired. The oil in the hydraulic part of the gearbox should be changed on every 60 000km.
