Exhaust gas recirculation (EGR) sends a measured amount of exhaust back into the intake to cut peak combustion temperature and NOx. On modern vans an EGR cooler often sits in the loop. Recirculated soot coats the valve, cooler, intake ports and swirl flaps — and short-trip trade use around Bournemouth and Poole accelerates that build-up.
Valves stick open or closed, coolers crack and leak coolant, and later common-rail vans add flaps, solenoids and sensors that throw their own codes. A light clean or a new valve can buy time. When the same EGR limp mode returns every few months on a Transit Custom, Partner or Transporter, operators start searching for van EGR delete Dorset options instead of another dealer bill and a day off the road.
