Help keep your charging system's output in check with the Standard Ignition Voltage Regulator VR-831. It is a direct-fit replacement for damaged original units and accurately regulates the charging voltage your alternator produces. It fits many Volkswagen and Audi models, among them the 2000-2011 Volkswagen Jetta, 2000-2009 Volkswagen Passat and 1999-2006 Volkswagen Golf. See the Buyer's Guide tab for the full list and engine details.

  • Direct-fit replacement: Replaces damaged original units and provides accurate regulation of the charging voltage the alternator produces.
  • Connectors and terminals: Built with OE-quality materials for an exact-fit connection to the engine wiring harness and designed for peak conductivity.
  • Housing: A high-grade plastic housing withstands both low and high engine operating temperatures.
  • Mounting sleeve: Made of high-grade anti-rust aluminum for an easy bolt-on fit.

The voltage regulator manages how much voltage the alternator sends to the battery and electrical system. Signs it may need replacing include dim or flickering lights, a lit battery warning light, or a battery that overcharges or won't hold a charge. The alternator, battery or wiring can cause the same signs, so diagnose the charging system first. If the original regulator is the cause, this unit replaces it.
