Broken Dipstick Piece in Sump - Audi

:roll:

I was checking the oil in my wifes Audi A2 last night and when i went to push the dipstick back down the chamber a small 1-2cm plastic piece at the end broke off. I am not sure yet whether the piece is still in the chamber or fallen to the sump. If i can get it from the chamber i will but if i can't and it ends up in the sump will it cause any issues or likely cause any engine trouble?. Do i really need to get the sump removed and the piece taken out? Thanks
