How to Replace the Fuel Filter on a Renault Scenic 1.9 DCI
When was the last time you changed your fuel filter on your Renault Scenic 1.9. DCI? It is recommended that they be replaced at least once a year. I bought mine 10 months ago and thought it time to replace it and at the same time show you how.
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.
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 manoeuvre. There isn't much play in the fuel lines either. Familiarise yourself with the connections before you start.
Top tip: Take photos of the parts in place before you remove them.
Removing the Old Filter
Removing the old fuel filter is easy enough, and Renault have 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. Again this fuels the need for a picture to be taken prior to removing the old part. I hope you pardon the pun there.....'fuel' the need.
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, in order 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 ?
Are you a competent DIYer ?
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.
See How the Renault Scenic has Changed
Motor cars evolve and change, none more so than the Renault Scenic 1.9 DCI.
Check out the video to see a 2010 demonstration model. The old Scenic was great but this one looks the business.
Fully equipped, these work horses are so versatile and very rugged. A must for family motoring in the 21st century.
With masses of room they make great touring vehicles. If you need to tow a trailer or caravan the powerful diesel engines are well equipped to cope with the extra strain.
Going on for what seems forever, the diesel power plant is virtually indestructible as long as you service them at regular intervals making sure to regularly change your fuel filter. As this article shows working on the cars of today can be quite tricky due to space limitations. Manufacturers cram a lot of engine into their cars and space is at a premium.
