2.0 tdi egr valve

[Jibberjabba]

Hi all.

My wife recently bought a 2.0 tdi s line 

Upon inspection (never removed the engine cover) 

It wasnt picked up that the pipes have been disconnected from the egr valve and a piece off copper pipe has been used to bypass the rubber tubes.

Why would someone do this has puzzled me.

Also its now started smoking a bit when you first start it up and drive it.

Could this be because the dpf is blocked.

Thanks in advance for any help recieved
