Hi there not long got my VW Polo 1.4 BlueGt and was thinking about changing my air filter and was wondering what this tube goes into and what it's for? do I need it?

I guess the positive crankcase ventilation

Aw ok thanks very much so there would be no problem from taking that away from air filter and changing the filter?

Do you mean that you would to change the type of air filter and the new one does not have a connection point for that pipe - so you intend to just leave it lying open - or are you just asking if removing and refitting that pipe after the air filter element is okay to do?

That air filter cover looks like it has been kicked around a workshop floor quite a few times? (why do people do that, it only takes a minute to place it on a suitable soft surface so that it looks like new?)

Edit:- maybe I'm wrong about the air filter cover, it looks like that car has been driven into a dust storm for its entire life!

Yeah wanted to change air filter and it doesn't have a connection point for that pipe so intended just to leave it in the open but wasn't sure if that would be ok :/

Yeah need to give it a good clean my road is very dusty nightmare for keeping the car clean

I wouldn't leave the PCV pipe unconnected since it's the only route for the (dirty) air out of the crankcase!

Cool I'll just leave it then thanks for the advice
