U059BInvalid Data Received From Hybrid/EV Battery Pack Sensor Module
- Generic OBD-II code · Network
- Can trigger limp mode
- How the car detects it
- The battery pack sensor module measures pack voltage and current and often sits in the switch box that holds the main contactors, reporting to the battery management controller. Audi uses U059B00 for an implausible signal from the high-voltage battery switch box on the 2024 Q8 e-tron family: after a stop at an AC charging point the car refused to enable its drive and the cluster asked the driver to stop safely, with contactor control codes P0ADC00 and P0AE000 stored alongside. Audi traced it to over-sensitive diagnostic software, advised a 20-minute bus sleep before towing and ruled out replacing parts. The 2025 Q5 e-tron shows U059B00 together with lost contact U029A00 (index entry only). CARB requires battery system faults that stop the pack moving the vehicle to be detected.
