Question about 2000 Audi A4
2000 Audi A4 1.8
Battery indicator came on and voltage dropped to 10V. AAA tech used portabel diagnostic indicator and determined alternator was bad. Car did run with a jump although at 10V. Towed to AAA certified mechanic. They replaced alternator. Voltage back at 14V for a few miles then battery indicator came back on. Voltage now at 12V. Do I need a battery? Is there a voltage regulator in the Audi? Could it be the alternator was not bad after all? I just want some knowledge before I talk to the mechanic about it.
Check the little wire that attaches to the back of the alternator it could be broke or hooked up wrong the wire should be connected to the passenger side prong

Take it to an Audi dealer. Could have been a bad alternator, and another bad alternator if they didn't use Audi part. Don't use cheap rebuilt Chinease stuff on your Audi.
