very easy, get a spanner on the aux belt tensioner bolt, turn the tenionser to slacken the belt, remove the belt, get a torx key on the timing belt cover bolts, remove the cover, then you can see the variator pulley, should take 10mins.
the lazy way is to only remove the timing belt cover bolts at the top and then prise the cover slighly away from the engine so you can watch the variator pulley through the gap.
