How to Clean the EGR Valve on an Iveco Daily

Model: IVECO Daily MK 4 - Years 2006-2020
Part: EGR valve

Let's see how to clean the EGR valve on an Iveco Daily. You will need a specific cleaner such as STP Diesel Engine Cleaner at £14.20 with free delivery in 1 day for Prime customers. Slightly warm up the engine, open the bonnet, and remove the air hose between the air filter and the throttle body. Start the vehicle again and maintain a steady engine speed using a throttle hold to keep the engine between 1,500 and 2,000 RPM. Insert the dispenser hose into the intake duct: ensure you spray towards the engine and not towards the turbocharger or intercooler. Spray the product at regular intervals, following the instructions on the can for the entire duration indicated (the video shows a process lasting several minutes). Reattach the air hose, start the vehicle, and let it idle for a few minutes, then take a short drive at low speeds and high RPMs; this helps expel carbon build-up and cleans the system.
