I.e those with power steering?

I have a part number of 6Q0 407 621 AJ, which is the 72mm inner bearing set for various engines including ATD (my old setup) and ASZ (my new one)

I've been told the vRS uses different inner bearings to other cras (bigger ones) but I'm sure I fitted the above part number back in December, but its started howling again. Does the vRS inner bearing have any extra strength properties over other inner bearings, and if so, what's the correct part number please? I was hoping to get a refund on the current bearing set as its only 4 months old.... Apparently the set I was supplied was not a vRS set, but to me they're all the same part. :confused:

which bearing exactly is it? i can look it up if there is a different number.
