Would this work on my 2004 Audi 1.8T quattro?

Best way to know is to look up your car at boschautoparts.com. That's how I got the current Bosch part number. Fits and works perfectly.

Is this the AFP up stream?

idk what AFP is but it's not associated with the catalytic converter

will it fit my vw beetle 2001 1.8 turbo?

Are you looking for downstream 02 or upstream 02 sensor?

Will this fit vw passat 03 -4cyl turbo ,? Some reviews say it does ?

It should fit. I put it in my 2002 Passat 4 cyl. 1.8T. Make sure you check the plastic adapter connector if that is with the same pin.
