Hello all I’ve been a long time listener first time caller and looking for any help. I have a 2014 ecodiesel with about 130k miles with no tunes no deletes. Kept up on regular maintenance, oil changes, filter changes without issue. Over this past winter I have had codes P0402 and P0299 pop up and can’t shake them. I’ve cleaned my MAP sensor and EGR Diffuser tube and the codes are still there. The tube and MAP sensor were fairly dirty and looking down in the intake when the tube was taken off it looked pretty gruesome. I’m at a loss and not sure what I need to look at next.

The recalls I’ve had done are as follows:

R69, V08, R23, R36, R40, T25, V44 and VB1.

You ever figure out anything about the issues you’re experiencing? I got something similar going on with my 2015 ecodiesel. I since have deleted it and still have the same issues.
