U0354 Software Incompatibility With Hybrid/EV Battery Inductive Charger Control Module

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

The inductive charger control module is the on-board part of a wireless charging system: a receiving coil under the floor picks up energy from a ground pad, and the module rectifies it and coordinates the process with battery management and charge controller. U0354 is stored when one of those partners finds that the module runs software or a calibration it does not accept, say after an exchange or a partial update. No maker documents U0354 publicly; wireless charging is rare in series cars. BMW ran such a system as a pilot on 200 California 530e cars (option SA 4VC) and, in SIB 61 23 19, limited diagnosis to dealers that own a ground pad module. Until the software matches, wireless charging stays unavailable; charging by cable and driving are unaffected. U014B means lost contact, U044C invalid data.

Likely causes

Inductive charger module replaced but not programmed or configured
Battery or charge controller updated to a level that expects other charger software
Software update of the charger module aborted

Symptoms

  • Wireless charging does not start
  • Charging warning in the display while cable charging still works
