Will an Audi A1 rear wiper arm fit an A3?

[Ash33]

I'm in need of a new wiper arm but the A3 one is quite bulky, i have noticed the A1 rear wiper has a flatblade wiper and was wondering if one would fit onto my A3? If not an A1 maybe a newer A3 or something neat.

Just do a rear wiper delete looks much better
