Tool for Alternator clutch pulley

[sabikeuk]

Hello,

I am just wondering if someone could advise which is right tool for removing of pulley from alternator:

Either

T50 torx: http://cgi.ebay.co.uk/Alternator-Pul...item255eae1954

or
M10 spline:http://cgi.ebay.co.uk/Laser-3307-Alt...item43a5027842

Alternator is VALEO, car AUDI A4 1.9TDI AWX engine 2002 B6

The only real way to find out which is fitted is to check. If you remove the plastic end cap with small screwdriver and then use a small mirror( Wife's ) with a torch you should be able to see whether the shaft socket has a 6 point recess ( (Torx ) or the 12 point recess ( 3 square or spline ) .
