Help keep your BMW's charging system at a steady, controlled voltage with the Standard Ignition Voltage Regulator VR-620. It is a direct-fit replacement for the listed applications, including the 1999-2002 BMW Z3, the 2001-2005 BMW 325I and 330I, the 2001-2006 BMW X5, and the 2004-2006 BMW X3.
A voltage regulator controls the alternator's output so the battery and electrical system receive the correct charging voltage. If a failed regulator is behind your charging problem, this unit is designed to replace it.
Signs a voltage regulator may need replacing: a lit battery or charging warning light, dim or flickering lights, a battery that keeps running down, or readings that suggest overcharging or undercharging. Other charging-system faults can cause the same symptoms, so diagnose the cause before replacing parts.
