Why Do I Need to Change the Fuel Filter?
Fuel filters need changing as they become clogged with rust from the fuel tank and system. Over time, water builds up from condensation in the fuel tank and can cause your car to have starting problems.
In my case, the engine had begun running lumpy (rough) and was proving slow to start. Changing the fuel filter did the trick. It also cleared the intermittent problem of the glow plug light remaining on after starting.
It is a good idea to fully understand what you are dealing with, so I would advise watching through the video within this article first. It is also worth saying that you are dealing with potentially flammable products in the form of the diesel within the fuel system. I would always recommend wearing gloves and goggles where necessary to protect yourself.
If you are not sure and perhaps you are tight for time it would be a good idea to seek further advice from a qualified technician or at least do the job when you have more time to complete it. The purpose of doing things yourself is to save money. If things go wrong then it is likely that there will be a cost implication so take care.
Where to Start
First you start by identifying your fuel filter and its location. If you look at the picture below you see it is located in the left side of the engine bay as you stand in front of the car.
You will notice that space is tight, so you don't have much room to maneuver. There isn't much play in the fuel lines either. Familiarize yourself with the connections before you start.

How to Replace the Fuel Filter
Here are some steps on how to replace the entire fuel filter. Follow the steps below to identify the filter in your engine bay and so prepare to replace it.
Removing the Old Filter
Removing the old fuel filter is easy enough, and Renault has colour coded both the filter and the fuel lines to make the process as easy as possible. If you buy non-dealer parts when replacing, you will see that the colour coding isn't present. This might give you another reason to take a picture before you remove the old part.
The great thing is that the new filter comes with those green stoppers, pictured. This allows you to plug the connections when you remove each fuel line. If you use them when removing the filter, you will not spill any diesel, other than the little bit which will seep out of the end of the fuel line.
When removing the fuel lines, you will need two screwdrivers, as detailed below, to press in the clips which attach the lines securely to the filter. Be careful not to break the plastic on the ends of the lines, particularly if doing the job in cold weather.

- Long thin screwdriver, flat-bladed
Will you do it yourself ?
Fitting the New Fuel Filter
Obviously fitting the new filter is less tricky than the removal of the old one.
The fuel lines should just snap back into place, but your two screwdrivers might be required if the clips on the fuel lines are particularly stubborn.
First Startup After Replacing Filter
When you start up after replacing your fuel filter, the engine may take a while to fire. This is due to the fuel pump priming and pressurising the fuel system again. So don't be concerned if it takes a few turns to get it started.
