Foot seal throttle valve MKB AKQ

Hello & good evening My name is Chris and I’m new here in the forum. Is my first Lupo. However, I had 2 Arosas and a Polo 6N before. So not completely undecided. Now I removed and cleaned the throttle valve during my new purchase (Lupo 75 PS 16v, 116tkm, EZ 98, engine identification letter AKQ). Definitely no mistake. I once heard that with the engine the DK spoiled quite quickly? Now it made me stutzig that I found there no foot seal. Can that be? And if yes, I can “room” the one from sealing paper myself , thanks in advance Chris
