Can you bypass the extra pipes on stock tdi intake?

[Ryan83]

Ok guys new here so appreciate if this is a daft question?
I have an A4B7 2.0TDI and have just put a K&N cone filter straight onto the stock pipe. Now my question is here. What is the extra pipe for on the intake and can it be bypassed? If so what pipe would I use as it reduces down at the engine? Appreciate the feedback if you can help

Possibly a secondary air pump, follow the pipe, as not sure they have them on B7 tdi's.

Thanks by air pump you mean air filter? I have no idea what that other pipe does tbh as can’t find anything online so thought I’d jump in here.

I'd have to check etka to see what it's for tbh, but the connector resembles air pump aswell as some breather systems on vag engines, if I get a chance I'll check back later.
