What changes
The engine unit re-learns the end positions of the throttle valve. Done after cleaning the throttle body or disconnecting the battery, when the idle is unstable.
Details
Factory routine 032E in the engine unit: the valve travels from stop to stop several times and the unit stores the positions. Takes about a minute; the app follows the status and reports completion. Any improvement in pedal response afterwards is temporary and not on every car.
Before you start
Takes about 1 min.
- Ignition on, engine off
- Accelerator not pressed — do not touch the pedals until the procedure ends
- Engine warm, no throttle faults
