bump a seven year old thread, nice! at least you used the search button.
It depends on what car you have, on the 1.9tdi pd engine its relatively simple - pop off the top cover have a look at the belt and realise that it just looks like a belt and unless theres actually something wrong with it then it'll look just like a belt.
My advice is just stick to the maintenance timetable and get it changed when its due but if your in doubt get it done - hundreds over thousands.
