Exhaust Gas Recirculation Flow Malfunction
EGR DTC Codes
All EGR-related OBD-II diagnostic trouble codes. EGR valve faults, flow performance, position sensor, cooler issues — with off-road suppression context.
About EGR codes
EGR codes indicate the exhaust gas recirculation valve, cooler, or position sensor is failing. EGR-off via ECU calibration is the most common chiptuning service — Softechpro disables EGR dosing, monitoring, and DTC triggering across every supported diesel and modern petrol ECU.
