Hey guys so after doing my Egr I had a lot of air coming through everytime I let off acceleration or before boost would kick in. After stuffing around and breaking a bolt. I undid the second bolt on the egr (first point where most people block) and the whole thing fell off. Seems the bolts at the bottom point have fallen off many moons ago. I was having some boost issues we could not pin point and low and be hold we have found it. So my question is what size bolts am I looking at for it? Will they be m10 and is that section threaded down there or bolt on the rear side. She's a tight fit with getting hands in there so I cant really tell what it would be.
