Hello all! I’m extremely new tonthe VW world, not new to diesels but definitely tomthe VW diesel world. Got my first TDI on Friday and when i bought it it sounded like it had some sort of air leak under acceleration. I’ve tinkered around with my cummins enough to fix things and underatnand what’s going on. I figured it might be a boost tube clamp or something loose. Well upon inspection the air is coming from the undernearh and it looks to be that damn egr cooler. Found a new one online genuine VW part for 245$. I hate these damn emissions crap. The hissing sound makes me pretty much 100% think it’s he cooler. Has anyone ever replaced theirs or deleted it? Any info would be greatly appreciated.
