Evidently, I have a air leak in either the intake of the intake manifold gasket. Mine is a 2017 ECOD 4x2 and the problem happened on my way to work one morning. The dealer wanted $5K to fix it, I elected not to pay them to do this. I paid for a tune and exhaust delete afterward, as a Diesel performance shop said he couldn't find the leak. He said this would "fix" my problem.....Fast forward to today, and I keep getting the P0299 code. Since I now know there is an air leak, I was going to try the intake repair myself, and understand the depth of the whole thing. What I can't understand is why it's not covered under the warranty. I have right around 50K, but I guess since it is not internal engine, its not covered. Any manuals or diagrams out there you guys would recommend here? I considered getting the Banks intake, but not sure, since it may not be the intake manifold.
