Overview
Owner-filmed repair walkthrough focused on the F0827 EGR fault code that throws the XR4155 into limp mode. Covers the full valve replacement (part cost noted at roughly $555, $570), the exact tools needed, connector and bolt locations, and a money-saving tip: disassemble the old valve first to check for a sticking motor before spending $600. Ends with a practical bonus showing how to use a cheap Bluetooth OBD2 dongle and the Torque app to read and clear codes without a dealer visit. Best for XR4155 owners, and likely Boomer 40 owners, facing the same code.
