There are even those who know they used _three_ belts - 113, 120 and 142
teeth.  Telling the last from the first two is pretty easy - telling the
first two apart at a glance is beyond my abilities, and I congratulate
you.

What it says on the invoice and/or on the box is not conclusive.

Because I've seen it before - exactly the same symptoms on an ur-quattro.
It's a classic problem because the parts are pulled at chassis (VIN)
level but quite a few cars have the 'wrong' engine in them.  It's also
possible to swap from 120-tooth to 142-tooth if you change all the
accessories - one car at least that _I_ know of has had this done.
