Model: Renault Clio Clio IV, MK 4, Clio 4 - Years 2012-2019
Part: EGR valve

Unfortunately, deposits on the EGR valve are common and can cause serious problems for your vehicle, so it is advisable to clean it regularly. This video tutorial will explain how to do it. The first step is to open the bonnet and lift the front of the car to access the valve more easily. The second step is to disconnect the electrical connector of the air pipe; using a flat screwdriver, unscrew the clamps of the air duct and remove it as shown in the video. Next, unscrew and then remove the air duct using a 10mm socket. Now, using a flat screwdriver, remove the power connector of the valve, and with a 10mm spanner, remove the supporting screws of the valve. Before extracting the valve, you must disconnect the inlet and outlet pipes of the coolant. To clean the valve, use a cleaner and a wire brush; before refitting it, pour injector cleaner into the reservoir. To install the valve, simply follow the same steps you took to remove it.
