F34 code soft close for trunk

Voda · 10-14-2025, 04:16 AM

Hi,

The tailgate of my F34 closes with a hard “thunk”. Is there a way to make it smoother?

I’ve seen ways of coding the automatic close on F15 or F10 similar to soft close of doors.

Does anyone know if it is possible for F34 and what parameters/values need to be written on HKFM?

thanks

I haven't personally done it but I know it's possible. Here's a video of someone coding soft-close on an F34 via Bimmercode:
