Hi All,

I know there are various threads/posts about on this topic, but most appear to be missing images etc now. So I thought whilst i was doing my own i would knock together a new mini tutorial with a few fresh pictures. Hopefully it will aid someone in the future!

Problem: The internal heater/cooler in the Laguna even at max speed were hardly blowing any air out of the vents, the air that was coming out seemed to be way off the temperature that it should be.

Solution: Replace the blocked cabin/pollen filter, behind the glovebox! (Price: £7.23 from eBay, time to fit: 15mins).

Tools Required: Screwdriver with a Torx 8 bit, Pointy nose pliers & Hoover.


Step 1) Open your glovebox, and with the draw down you will see at the top middle a single Torx 8 headed screw, remove this. as seen below.

There are 5 retaining clips on the glovebox liner itself - three along the bottom edge and two at the top + one positioning pin, the liner is easy enough to remove with your hands and no tools, however you could use a flat head screwdriver to 'gently' prise it away, be careful not to snap it. The clips look like the below:

Step 2) With the glovebox liner removed you can now see the cabin filter housing as seen in the pictures below. With you're pair of pliers grip the front of the facia on this housing and gently pull it away, there are four tiny clips holding this in place and with a little wiggle they should just pull away (again pictured below). Note: Pre-2005 models have two tiny bolts holding the facia in place, remove these first.

You should now be able to see your clogged and disgusting looking cabin/pollen filter, like below:

Step 3) Take your pliers, have the hoover to hand (it gets VERY messy) and grip the old filter and pull it out, you will need to distort the filter to get it out with any ease, i had to hoover the the muck out as i was pulling at the filter as it was that built up, it was jamming the old filter as i was pulling at it. after 2/3 minutes of hoovering and pulling it came out. You will be left with something that resembles the below pictures... Be sure to clean up all the debris that is left behind and if possible hoover out the fan unit located below the filter (provided your hoover will fit in the gap - otherwise you'll need to use your hands), as debris DOES drop in here and it will rattle and make a weird buzzing noise if you leave debris in there and put it back together.

Step 4) With the old filter removed and everything cleaned up - its just a case of sliding in your new filter - like the removal process, you will need distort the filter slightly to get it back in the slot, be careful as some of the replacements do have an air-flow-direction, others are bi-directional - this is indicated by an arrow printed on the side of the filter itself.

You should then have something that looks like the below.

Simply clip the filter housing facia back on now, and replace the glovebox liner (both of these just click back into place) then put the single Torx 8 screw back in.

Job done ! Just bin your old filter and give yourself a pat on the back and enjoy the powerful breeze and accurate temperatures of your heating/cooling system! :D

The pollen filter change @ 18k is part of Renault's procedure, however dealerships from what I've seen, will quote a price for a service which for better looking ££s omits the pollen filter.


To get round this, after a price for a service had been agreed, I always used to say.

BTW don't bother changing the pollen filter, leave it on the back seat, I'll do that when I think it's needed myself. :d
