So, my replacement alternator has arrived (thanks for the link to the supplier, Mike) but I need to call them with the part number to check it’s the right one before I have it fitted.
Can anyone oblige please?
Thanks, Jim

From what I can see you should have a 150a Bosh alternator.
Looks like all these part numbers should work.

Thanks for the replies. I already have the replacement alternator but I need the original Audi part number to double check before I fit it. The VIN is WAUZZZ4D63N001186

Yep I looked now as far as I can see those numbers are the ones. Does that match you alternator. Also just curious is yours an Audi exclusive spec?

My S8 is a ‘final edition’ (UK only I think) not an exclusive

077 903 015K is for the S8. 077 903 015P is also compatible.
059 is a diesel, 078 is V6. Many sellers will claim the V8 and V6 are the same but this is incorrect.
