2011 to 2016 Audi S4 – How to launch control

January 4, 2017 in Audi A4, Audi A4 B8 (2007 to 2015) by admin

The launch control on your 2011 to 2016 Audi S4 S-tronic provides the best acceleration possible when starting from standstill.

To enable it, first make sure that the engine is at normal operating temperature and that you have the stering wheel facing in straigh line.

Step 1. With the engine running, press the ESP OFF button. The ESP Off light in the instrument cluster will appear with a message “ASR Off Caution! Limited driving stability”.

Step 2. Move the gear selector lever to the S position.

Step 3. Press the brake pedal strongly with your left foot and hold it down.

Step 4. At the same time, press the accelerator pedal down completely with your rightfoot until the engine reaches and maintains a high RPM (3000 to 4500 rpm).

Step 5. Within 5 seconds, remove your foot from the brake pedal and… there you go!

Be aware that the transmission temperature may increase considerably after using the Launch Control Program. If that happens, Launch Control will be unavailable for a few minutes. It will be available again after a cooling period. When accelerating using the Launch Control program, all vehicle parts are subject to heavy loads. This can result in increased wear.

Only use the Launch Control Program when road and traffic conditions allow it and other drivers will not be endangered
