Do you have a picture of that red ones engine bay? Because I'd like to know how they fit a 5 cylinder engine into a Polo. I'm also curious about how they got the displacement down to 1,8 litres, as the smalles VAG 5 cylinder I know of was a 1,9L with a carburator... so with 2 valves per cylinder only.
Are you sure they didn't tell you something about a 1.8L 20V four banger?
