X35 System updating process
MAHLE X35 Systems require a special device called MAHLE GCU to be updated correctly, so we recommend that you contact your authorised dealer to carry out this update process properly. Latest firmware version available: V Q4.3 Released October 2023 which replace V Q3.2 released September 2022 and all the previous versions.
How to update your X35 bike

- Intermittent purple: Auto-updating, please wait
