Keep your Mercedes-Benz charging system steady with the Standard Ignition Voltage Regulator VR-844 (also written VR844). This voltage regulator controls the charging voltage the alternator produces, and it drops in as a direct-fit replacement for a wide range of Mercedes-Benz models, including the 2001-2006 CL500, 2003-2005 E320, 2002-2008 G500, 2008-2009 GL550, 2000-2006 S500 and 2005-2009 SLR McLaren — see the Buyer's Guide tab for the full 21-application list and engine details.

  • OE-quality contacts: Each connector and terminal is built with OE-quality materials for an exact-fit connection that restores peak conductivity to the engine wiring harness.
  • Accurate regulation: A direct-fit replacement for damaged OE units, it helps deliver accurate regulation of the charging voltage the alternator produces.
  • Heat-tolerant housing: High-grade plastic housing withstands low and high underhood operating temperatures.
  • Bolt-on mounting: The mounting sleeve is made from high-grade anti-rust aluminum for an easy bolt-on fit.

If a failed voltage regulator is the cause of over- or under-charging on your Mercedes-Benz, this unit replaces it.
