Audi A4 Quattro 2.8 alternator

I see there are 2 available alternators for this car at the parts stores- I haven't torn down yet because I want to do it all at 1 time -remove, replace- Done. But I am not sure which alternator I need. everything on the car is stock- no need to beef up the alt for stereo etc.
Do you know how to determine if I need the 90 or the 120 amp alternator?
thanks in advance

Did they specify that both of those were for the A4 of your model year, or could one have been for the S4 (the twin-turbo version of the A4)? If they're both for the A4, I'd think that logic would dictate that the 120 amp unit would be for the 2.8L and the 90 amp unit for the smaller 1.8T engine. I'm not positive, and I've yet to come across discussions of this on the Audi boards, but that'd be my bet.

With volt meter on battery start car and read voltage. When yo first put the meter on a full charged battery it should read between 13-15 volts. When you first start motor the voltage should go 3-4volts higher then when you first put it on. And then tapper down after awhile. If there is no voltage increase after start alternator is out.

Battery indicator after new alternator Audi A4


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.

1996 audi a4 transmission hard shifting


Get the transmission scanned at the dealership. If it has incorrect gear ratio code stored, it needs a transmission. Only the torque convertor or valve body can be replaced for any repairs at the dealership, so it needs to be diagnosed correctly. Any authorized ZF transmission repair shop can also repair them, more than the Audi dealerships can, so thats another alternative.
