Overwriting Adaptation Values: Information
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2018 Porsche Cayenne, 2017 Porsche Cayenne, 2016 Porsche Cayenne, 2015 Porsche Cayenne, and 2014 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
Consequences of Tester adaptation if conditions for automatic adaptation are not met (violated boundary condition):
- For a fault entry in the load detection range (P0068 + P1069... P1077), the limits are extended in order to prevent incorrect detections.
- This extension is cancelled if an adaptation is performed when the conditions for automatic adaptation are met, or after 15 warm-up cycles at the latest
- (Warm-up cycle = coolant temperature increases by more than 23 °C (73 °F) after start-up and reaches at least 73 °C (163 °F))
- Following manual throttle valve adaptation when ambient conditions are not met, throttle valve adaptation is carried out again automatically as soon as the ambient conditions are met.
- There is NO 30-second waiting time here, but a slightly delayed engine start is possible once.
- The ambient conditions for automatic adaptation are as follows:
Engine off and ignition on for > 30 seconds.
Accelerator pedal is not pressed.
Vehicle is stationary.
Power supply for throttle valve adjusting unit is OK.
Coolant temperature 5 °C... 100 °C (41 °F... 212 °F)
Intake air temperature 5 °C... 40 °C (41 °F... 104 °F)
The accelerator pedal must always be pressed after approx. 1.5 minutes since each adaptation step is limited to 5 Nm.
