2.0 tdi egr valve in Audi A4 (B7) Forum Posted September 27, 2020 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 VID-20200925-WA0011.mp4
