Thread: Disco-1 TDI Alternator Compatibility with other Vehicles

I did a Google search on this before buying a new one. Dug through a bunch of other forums in Oz, UK etc, and the only thing I found were ones requiring modification and no straight bolt-up. Given the standard unit is 100A, it is pretty decent, so I decided to stay stock just to save the screwing around with fit and alignment. As a note, the one thing I did find when I bought the OEM (Denso) unit, it came with a smaller pulley - which I thought would be fine as it all lined up and took some strain off the belt, until I found the revs were 500rpm out on the tacho. I forgot the tacho gets its signal from the alternator. So something else to consider with your compatibility question.

Thanks for the heads up on the Tacho. I've seen it mentioned in a couple of posts but they never mentioned the connection :-)
