Bulletin number: TB-09-10-02
Component: Electrical system: alternator/generator/regulator
Summary: Volkswagen: headlights may intermittently dim slightly at idle. At idle speed the alternator voltage can fluctuate, as the alternator cannot fully compensate the fluctuations. Some electric consumers come on in cycles or have no constant current consumption, which amplifies this effect. The load condition of the vehicle battery can also influence this effect.
