How do i clean my EGR Valve?

Ok this is a pic of the 1.9 Engine bay..

You will see the EGR valve located to the left of the Airbox/Airflow meter..

Do NOT remove any connectors with the ignition ON as the Service light will come on..

To remove the valve you need to remove the Large Black Induction Pipe to its right.. It is attached by two \"jubilee\" clips with 7mm ends.. Loosen the clips enough that you can pull the pipe out of the engine bay..

Detach the Large Grey connector that is plugged into the end of the EGR valve.

The Valve is held in place with 3 10mm bolts.. Remove the bolts, taking care not to drop them onto the undertray or gearbox casing..

The valve is then pulled out of the exhaust manifold.. But it will be very tight.. I use a large pair of Pipe pliers and carefully twist the valve back and forth until it starts to loosen and gently withdraw it at the same time.
The valve will only turn 20 or 30 degree in either direction.. But it will with some persistance come out..
There will also be a metal gasket on the valve.. This can be used again or get a new one from Renault.

You can use a number or cleaning agents.. Some of these are brake cleaner, Carb Cleaner, Paraffin, Petrol etc.. I generally use an old tooth brush and dip it in the cleaner and clean the sooty deposists from the valve.. If the soot is hard then soak the valve in the cleaner, but DO NOT completely submerge it.. Important: Do not get any dirt or cleaner on the connector..

When you are satisfied with the cleanliness of the valve, then refitting is the reverse of removal.
