What is this for? Polo 6N. Air filter pipe.

Post by craigedmonds »

Today I was changing the air filter and I noticed that the previous mechanic had bodged the outpipe coming from the air filter cover.

However, that pipe goes into a box of some kind. I noticed some carbon build up in that box when I removed the pipe.

Can anyone tell me what that box is for?

Below is the bodged pipe and under that is a picture of the inlet for the pipe which leads to some kind of box in the back of the engine.

Thats the crankcase breather. The bit in the hose with the plug is the heater for the crankcase breather
