Smart Charging — Test Battery First
The Jetta uses a smart alternator with regenerative charging. A weak battery forces the alternator to overwork, causing premature failure. Always diagnose battery health before replacing an alternator. At 4M Car Care we test both with a VW Group-compatible tester before recommending any replacement.
