Question about 2002 Audi A4
Hi the battery voltage on my audi a4 is very high when driving it goes over 14 volts and over 16 volts when i go up to 70 mph.
when the engine idles the battery warning light comes on. thanks
Voltage regulator is going bad. Have alternator tested or go ahead and have it replaced. Also this would be a good time to have the battery tested. Usually an alternator that is over charging will "cook" the battery causing it to not charge, not hold a charge, to losing the gel/electrolyte solution due to boil out.
