MB Sprinter check engine light and code P0402
DW & I picked up a second MH Easter weekend from my mother, a 2016 Thor Siesta 24SR. The check engine light was on while driving it home. Extracted code P0402, EGR Excessive Flow Diagnosis. Searched the net, and found videos showing how to remove, clean EGR with brake cleaner, and re-install it to solve the issue. Well, it worked. I removed the EGR, and it was very sooty. Sprayed it clean with brake cleaner, re-installed the EGR, and was able to clear the fault. It has remained off for the past 160 miles.
EDITED: I should have placed this post in repair section. Moderators, please move this from MODS to Repairs.
