Audi only specs a replacement _distributor_ for the 200q20v.  The new distributor will arrive with a smaller rotor (054 905 225) and a metal drive gear, plus new dist. cap.  The rotor they are trying to sell you has a wider tip, and is used on the non-motronic cars (virtually all previous model and normally aspirated cars, I believe).  They are looking at the wrong spot on the fiche, I'd say.

The dealer is wrong, and the bosch cross-reference book is wrong (it's also wrong about plug wires, btw; they send wires that won't fit the car, btdt).

The (wrong) wider dist rotor tip has been blamed for some cross-firing at high rpm modified motors, resulting in engine destruction (bent rods, etc.).

Call Rod at thepartsconnection.com and ask about the correct rotor; he's gotten them in the past from Germany.  Yes, stock rotor is glued in place, and must be re-glued after removal.

People have installed the (wrong) wider rotor, and used it for long periods without a problem... but if you mod the car, you run a big risk. The correct part is around $18? so it's not a huge expense.
