U0411 Invalid Data Received From Drive Motor Control Module

U0411 is stored when a controller, typically the engine or hybrid controller, receives messages from the drive motor control module (the inverter electronics of an electric traction motor) that it judges invalid. Volkswagen lists it in its 2014 hybrid OBD charts: for the Touareg Hybrid on implausible messages from the motor module, for the Jetta Hybrid on an incorrect CAN data length code. Bentley's Flying Spur Hybrid (2022-2023) stores U041100 in the engine control unit with a warning lamp, partly together with P0A2E for the motor temperature sensor circuit, and has the technician measure and inspect a harness connector. U0110 means lost contact, U0311 a software mismatch. Hybrid drive may be limited or switched off.

Likely causes

Damaged pins or poor contact in harness connectors near the drive motor (Bentley case)
Faulty motor temperature sensor circuit making the module send invalid data
Software of motor module and hybrid controller do not match
Drive motor control module internally faulty

Symptoms

  • Engine or drive system warning light on
  • Electric drive unavailable, engine runs constantly
  • Reduced power
