Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Function of Air Springs: Post-mode
Post-mode is activated in order to compensate for any inclination or to adjust the ride height after driving and between the Pre-mode and Sleep mode.
Duration of Post-mode is limited to approximately 1 minute. This mode is only executed if the engine has been running before the system switches into this mode. If the engine has not been running, the system switches directly from Pre-mode to Sleep mode.
Control adjustments are made within a tight tolerance band using the following coding parameters:
| Coding parameter | Value |
|---|---|
| niv_post_up_e | - 59 mm |
| niv_post_up_d | - 07 mm |
| niv_post_down_e | + 06 mm |
| niv_post_down | + 04 mm |
The fast signal filter is used.
In the event of an inclination (Kerb mode), the control operation takes place for the nominal heights applicable in this situation.
