Just wanted yalls advice on this question. Will a 2012 a8 4.2 alternator work in a 2008 s6. 5.2 ? Voltage and amps are the same as well as connectors. I don’t see why it wouldn’t be an issue other than removing the different coolant connectors and replacing them with the originals from the old one( becuz those are different )
it looks like they are different part numbers and have different mounting bracket patterns

They have the same mounting styles though. The only thing different is where the positive wire mounts and the connector is located. I just don’t see why it wouldn’t work. I’m asking because I found a barely used alternator for 95 dollars. Cheapest reman I seen was 250 plus tax and core ( all that bullshit extra shit )
