Keep your charging system informed with the Standard Ignition Battery Current / Volt Sensor BSC57, a plug-in sensor that monitors the current flowing into and out of the battery and reports the battery's charge and discharge to the vehicle's charging/energy-management system. It installs as a direct-fit OE replacement, engineered for proper fit, form, and function on the 2016-2023 Audi TT Quattro (L4-2.0L). Listed under both names — Battery Current Sensor / Volt Sensor.

  • Direct-fit OE replacement: designed to drop in for proper fit, form, and function for easy installation.
  • Accurate measurement: high-quality components measure the battery's charge and discharge.
  • 100% tested: undergoes full testing for performance and reliability.
  • Quality-controlled build: produced by a global manufacturer with quality control maintained throughout the process.

If a faulty current/volt sensor is the cause of a charging-system warning light, inaccurate state-of-charge readings, or start-stop trouble, this replaces it — diagnose the cause before replacing, since these signs can have other origins. Connection is through one oval female plug-in connector with three male bullet terminals. Country of origin: Romania.

Interchange: none listed. Manufacturer part number BSC57.
