Car Broke down! :/ after full revs Any help /advice?
I struggled finding a new alternator for my S2 Avant but your local Bosch Auto centre can supply a factory refurbished one for £200. Mine looks like a brand new unit and was a perfect fit. They need an exchange unit. Suggest you attend your local breakers who I'm sure will provide you a broken Audi one cheap as chips

No! Point 4 relates to the fact that the alternator fitted according to the Bosch part number you were given is also internally regulated and therefore not capable of being controlled externally. Its relatively easy to verify if you do a bit of checking. You can then confidently rebut the lies you are being told with facts. The A4 B5 model that alternator fits is also not capable of controlling the voltage of an alternator. Like the correct S2 one, it is also internally regulated! From what I can tell this capability is not possible without Canbus and our vehicles are from the wrong century.
The problem really I think is the pulley which is probably unique. Which is why I have been banging on about getting it back unless it has been fitted to the alternator on the vehicle. As I said previously and others have proved from the threads linked to, the alternator itself is a common fitment on other models of Audi from a similiar vintage. The difference in the part number represents partly the model designation and the differences in the rear cover and pulley. For example the alternator was also used on the S6 C4 with changes to the pulley as it ran a 6 rib belt whereas the S2 used a 4 rib belt.
If the pulley has gone it will never function as intended. Although if you want someone to bodge something back on, then that will also be possible because as long as its attached with a belt and hooked up to the car correctly then it should generate voltage/amps when spun. So basically you need to work out why, in your case, this has not worked.

If you look through the parts that constitute the alternator fitted you will see the Regulator. That means that alternator is internally regulated and not as suggested by any other means.
This is so obvious that alternator on our cars is regulated internally.we talking about car from 90s that has not got any communication network like CAN bus or LIN .if it was controlled by ECU it would have battery monitoring module fitted on negative post on battery with communication line connected to it that can report back the message of battery state of charge ,temp another info and base on this the charge output would be regulated. This is not the option on S2 I'm 100%sure
That's great news Chris. Pleased your getting things sorted out. Regards Lynn
Thank you buddy! yes!! sorry! I must get to the stage of cambelt change so I can return your tool for you! Huge thank you for helping me out!! ... onwards!! <3
Have a close look at the metal where the missing bit used to be. The refurb process will take a nasty horrible dirty alternator body and likely degrease then vapour blast. The vapour blasting leaves the as new finish and a slight smoothness to the surface. If that smoothness appears across the jagged edges where the missing metal once joined, the bit was missing before it was refurbed and won't be inside. If it is a fresh looking break then it could be inside and would likely rattle.
I don't think I'd run an alternator with a bit rattling around inside it but if it's just missing, it's not really a big deal other than the implications for quality control.
