    Alternator details

    Im having the same problem as alot of others, ie low charge voltage and also battery being drained when engine switched off which is I presume the diodes broken down and allowing the alternator to act like a motor and drain the battery .

    Im not going to bother trying to repair mine as its 13 years old and fixing could be false ecconomy.

    what I would like to know is with the s2 deing fairly rare what other Vag group cars have the same alternator so I can look further afield. ??

    The V6 engined A80 models share a similar 120A alternator, although the part number differs so I can't guarantee they are 100% interchangeable.

        It would appear that your car has the incorrect item fitted at som point in its life.

          why do you think that?
          seems fine, never had a flat battery. I haven't got a/c or electric seats etc so maybe it was just fitted to S2's that didn't have all the toys??

            anyway, just imagine all that extra hp i'm getting by not whizzing round an over-sized alternator - 0.2 bhp perhaps???!!!

              I'm pretty sure all ABY had the 120A alt as standard regardless of the options pack.

                Correction: it actually depends on the chassis number FWIW
