Coding and Programming Requirements

Adaptation or initialisation should generally be expected after replacing this battery-monitoring sensor module.

Audi-compatible diagnostic equipment may be required to train or adapt the replacement sensor, check communication with the vehicle and clear stored fault codes.

If the vehicle battery is also replaced, the new battery may require registration or coding so the energy-management system can account for its capacity, type and condition.

Component-protection removal is not normally associated with this sensor. Exact diagnostic requirements depend on the vehicle and installed battery-management system.

Installation Information

Professional installation by an Audi technician or qualified automotive electrician is recommended.

The vehicle battery must be disconnected safely before replacement. The battery terminal, cable connection, earth point, wiring and communication connector should be inspected for corrosion, looseness or damage.

After installation, the charging and battery-management systems should be diagnostically scanned and tested to confirm correct sensor communication and electrical operation.
