542006, Warning - Identical gear detected – Your eShift automatic system has detected an error.
Shifting possible
Error:
The Bosch drive unit has incorrectly learned two identical gear ratios. This gear-learning process is part of the system's optimization of the walk-assist function up to 3.5 km/h.
Result:
- Shifting gears remains possible
Error correction:
An update will be available via the Bosch Flow App starting July 14, 2025. The following troubleshooting will then no longer be necessary.
To rectify error 542006, the eShift functionality must be removed via the Bosch DiagnosticTool 3.
Required procedure (to be performed by an authorized dealer):
Disconnect the connector of the E-14 shift unit in order to intentionally trigger error code 1C7410.
With the E-14 unit still disconnected, connect the bike to the Bosch DiagnosticTool 3.
Navigate to Diagnostics & Configuration and remove the eShift configuration.
Power off the system and reconnect the E-14 shift unit.
Upon the next system start-up, the error will no longer be present.
Finally, ride the bike with motor assistance and shift through all gears to allow the system to re-learn the gear ratios.
E-14 system can continue being used
