Hi Guys

I have an a4 avant s line 2.0 tdi 2006

There is a problem with the heat exchanger as the connection to it (flexible egr pipe) and the connection to the manifold are not secure (bandaged and sealant used)

I was wondering what the technical names for these parts are so I can order new ones and get the car repaired. I have attached a couple of photos trying to outline the problem.

Thanking you in anticipation.
