The expansion of the ZF8HP family continues on newer-generation BMW applications.

04.03.2026 — Upgrade 2.94

The designation ZF8HP50 identifies the evolution of the automatic transmission installed on models from 2015 onwards, where KESS3 enables OBD programming of the Bosch ZF8HP50 TCU. This allows direct, safe, and non-invasive intervention on transmission management.

In the workshop, this means being able to work on shift strategies and software restores with a streamlined operational workflow, on a vehicle fleet that remains central to the market.
