General information
For different reasons it can be necessary to change the closing force of the tension springs, e.g.:
- Frequent parking uphill or parking in two-level garages (tailgate does not remain in open position)
- Customer complaint of operating convenience when opening and closing the tailgate
- Retrofit/dismantling of accessories on tailgate (e.g. rear spoiler, warning triangle, etc.)
The closing force can be changed by reattaching the tension spring at the rear holder.

IMPORTANT: It is not permitted to change the attachment on the hinge.
Adjustment positions:
1. Soft (factory setting without rear spoiler)
2. Medium
3. Hard (factory setting with rear spoiler)
Adaptation of the closing force:
- Check the position of the tension springs on the left/right
  NOTE: The left/right tension springs may be attached in different positions. Exception: Position (1) on one side and position (3) on the other side is not permissible. This causes tailgate inclination.
- If possible, firstly reattach the right tension spring in the next higher/lower position
- Check the closing force
- If necessary, reattach the left tension spring in the next higher/lower position
- Check the closing force, repeat the process as required
Re-attach the tension spring. Refer to REMOVING AND INSTALLING/REPLACING LEFT TENSION SPRING FOR TAILGATE (M4 COUPE, M4 CONVERTIBLE) and REMOVING AND INSTALLING/REPLACING RIGHT TENSION SPRING FOR TAILGATE (M4 COUPE, M4 CONVERTIBLE) .
