The only different wings for the 6N2 are those fitted to the 1.6 16v GTi all others are the same https://volkswagen.7zap.com/en/rdw/polo+derby+vento-ind/po/2001-240/8/821-821010/#1 

8valve polos from the 1.0 and1.4 are longer towards the cill and won't fit a 1.4 16v, 1.4 TDI or 1.6 gti.

16v and TDI were shorter in length. Gti ones and 1.4 16v fit the TDI. It don't matter if 3or5 door as same. Only difference is the long length down to the ground next to the wheel . Fact.
