Hello everyone, Today i noticed that something is messed up with my EGR cooler unit. The hoses are all rewired and not going to the cooler. Why is this and how can this hurt my engine ? The car is an audi a3 2.0 tdi BKD 140hp 2004 I know the photo is poor but you can see the 2 pipes are hosed together and the big hose is not going to the egr cooler but connected with another hose going who knows where. Any thoughts are appreciated! I saw something similar on EGR deletes, but my egr valve is in its place and looks factory like.
