thanks crasher for the reply,why was there two different makes? did it change at a certain year?just interested because i was sold a pulley remover tool today, and the m10 spline which holds the alternator from spinning was to big.

could be down to age but prob down to spec level

Many manufacturers dual source parts so that in the event of a supply problem with one maker production can carry on with parts from the other . Also it helps to negotiate prices as the two makers are in competition.
On the MK5 its quite easy to see which alternator is fitted. If you use a small mirror and focus on the black plastic RHS voltage regular part of the alternator you will see the makers name and P/No. I know this because I've just done it on my daughters car ( 1.9 PD TDI). Her 05 reg. was a Valeo 140A VW part No. 06F 903 023C

Does anyone Know the correct tightening torque for the Alternator free wheel pulley ? Is This torque value on ElsaWin ? Is it 48 ft.lbs / 65 Nm ?
I can't afford to take chances on daughters' car !
The VW Part Number of the pulley is 022 903 119C.
Thanks
