Alternator OEM Audi or Bosch

Voltage regulator is built into the alternator. If you're seeing 14.5 V with the engine running it's as good as it is going to get.

ran this one a bit in my 88 16v scirocco. works fine. a bit biger than the sotch as far as size.

A few hard lessons I learned: Have a voltmeter and ensure your battery is good, a bad battery will kill a good alternator (12.6V min on non running car) Find a reputable guy that rebuilds starters and alternators and try to get your alt rebuilt or find a new Bosch.

I would try replacing it with a stock Bosch alternator.

Got it. So am I correct in thinking that these Bosch alternators have both diodes to get to DC and voltage regulators to make it a clean voltage?

Welp... the alternator AND the battery are dead. New battery is in, now to do the alternator but I need food first. I was amazed that the store had a rebuilt Bosch alternator IN STOCK

I am pretty sure that the 120A-Vr is much like all of the later Bosch alts with internal cooling. I just took my 120A 1.8t one apart and it is a PITA.

okay just did mine 14.7x after a cold start...can it be too much ? does that sound reasonble

I figured alternator, so took it to Autozone to scan and everything passed. Then took it to Meineke for them to check and they told me alternator was bad and replaced it. Well my interior lights were still flickering so I took it back and they say seems like the one they installed was defective, so they replace it again with an OEM Bosch and also print me a printout of a bulletin stating that under load lights may flicker and there is no solution.

A friend had a rebuilt bosch unit that he lent me to try and that too doesn't put out any voltage.
