C5 X7 Pollen Filter Replacement & Air System Clean How To
I thought I would post up a 'How To' on replacing the C5 X7 Pollen Filter and Cleaning the Air Con / Air System, specifically for the Right Hand Drive model, as the very few You Tube videos on this are for Left Hand Drive vehicles and are generally not in English. Citroen Service docs don't really help much either as they show the process for a Left Hand Drive model with pedals and different trim, as of course the heater components remain in the same place.
What You Will Need:
A Torx 20 Screwdriver
A Small Flat Blade Screwdriver
A Pollen Filter (Part 6479 45)
An Air Con Bomb or Similar (only if you are cleaning the A/C system) Air Con Bomb / similar Link
A Bright Torch
A Hoover
A Hot Bath Afterwards
First of all there are 2 plastic screws under the passenger side glove box at the front that need to be turned 90°. On the right edge of the trim, you will see a snap connector - push this in and the trim will loosen. Be careful as the footwell passenger light (if fitted) will be attached. Using the Flat Head screwdriver, gently push in the small plastic lug of the Footwell Light and lever it out so that you can access the plug. Disconnect the plug by pushing in the lug and pulling. With the top trim removed, you can now see the Pollen Filter cover through the exposed recess. We will need to remove the right hand side trim to get further access. Undo the Torx screw. With the screw removed, gently slide the side trim forwards. There are 3 locating pins. Locating Pins: Now Assume the Position! VERY GENTLY pinch together the bottom 2 lugs to release the Pollen filter Cover. Once disengaged the cover will easily pull away. Note: There are 2 holes on the cover that are to allow the cover to be screwed back into place if you inadvertently break the lugs off
Now, get your torch in place and gently pull the filter out - be warned there will be a load of crud and bugs flying out as the old filter springs out! As You pull out the filter, try and roll it, whilst pulling gently as there isn't a lot of room to pull it out directly. Whilst we are here - this is the Heater Matrix Location! ... and the Heating Resistance unit - hmm, 2 Hours, 8 Minutes and 56 seconds on the label ??? - G7192002 is definitely the Heater resistance. perhaps that is the date and time is was made - how precise! And while we are still here, this is the Blower Motor Control Unit that you can just see up through the Pollen Filter housing (arrowed in Yellow). A better close up: Back to the job at hand - here's the grotty filter in all it's glory: Do I believe Citroen changed this last service... I don't think so Out with the big guns - time to hoover out all the rubbish. 'Bugs be Gone' We bought the car kit with our Dyson Animal - it has a bendy crevice tool - great for getting into the recess at an angle. Now for the Air System Clean (whilst the filter is out) Read the instructions carefully, as you don't want to be in the car when this goes off. These all work similarly, but basically, move all seats forward and tilted towards the front of the cabin. Close all windows and doors. Start the engine and use the following settings:
All Air vents Open
Ensure Air Distribution is Generalised throughout the car
Fan Speed Full
Set Temperature to coolest Level
Air Con On
Switch to RECYCLED AIR Mode
Place the Air Con Bomb in the Rear compartment on the floor in the middle. DO NOT activate it with your face looking down at it - Activate it from the side, then leg it and close the door. Wait until the Bomb has fully discharged itself, then wait another 5-10 minutes before opening the doors.
Enter the car and switch off the engine. Put the seats back and the passenger seat down to help with the acrobatics necessary to get the new filter in. Look at the notes or instruction either printed on the filter or on the instructions - the filter is designed to operate only one way and should be positioned so that the air flows correctly from the front of the car to the back of the car in the direction of the air flow as per the arrows: Get your torch again, and with the filter in the correct position, you will need to flex it gently, angle it in through the top, then at the bottom, wiggling it up and down as you gently push it in. Just keep using your fingers to push at the top and bottom equally until it goes in. Once in, pull it out slightly and give it a wiggle to help ensure that the concertina has expanded and that the filter is fully in position. Place your cover back on, and gently squeeze the clips, position the cover and release the clips. If you have broken these - you will need to use a couple of small screws to secure it back on. Slide your trim back on front to rear, ensuring the 3 pins locate properly, then screw back up once in position. Next thread the wiring plug back through the top trim, re-attach the Footwell Light and snap into place, position trim, click the snap connector into position and do up the trim screws. Job Done
Bath!
I can't really put a time on the job as I was taking pictures and had to wait for the chemicals to dissipate, but if I was doing the filter only, I would say about 30 minutes at least. Most of that is getting the old filter out, cleaning up and putting the new one back in.

Thanks for this, looks like something I might even be able to manage!
Cars in Wednesday for a full service. What filters would you expect to be included? You mention Citroen didn't do it - did you pay for it to be done and they Judy didn't do it?

Re: C5 X7 Pollen Filter Replacement & Air System Clean How To
Well That's what I think - because I have it regularly serviced with them - They are supposed to be replaced every 15k Km, so it is possible - but I think from now on I will Check myself - I've put a mark on the filter, so next time I want to check I'll know. They do different things at each service - so hard to say, but I'm glad I did it - the system is working with a new lease of life now - warp speed!

It's hit and miss with main dealers. The Scenic went to Renault for a full service at £150 and only got an oil and oil filter change.hoggers wrote:

To me a full service is oil, air and fuel filters. Plus oil, spark plugs (on petrols) and whatever else is on the service schedule for the particular car at that age/mileage. It should also include checks of brake, pas and all other fluids with top ups if necessary handbrake adjustment, oiling and greasing of moving parts like door hinges, pedal pivots.
I'm yet to see a full service from a dealer I approve of, some independents do a fine job though in my opinion.

Re: C5 X7 Pollen Filter Replacement & Air System Clean How To
Nice guide Marc. It looks very similar to replacing the filter on the Mk1 from what I remember although I didn't have to get upside down.
It's good to know that the resistance/control unit is on the passenger side this time as the heater blower decided not work on my car yesterday morning just when the inside was full of condensation after a cold night. I hoped that it return for the trip home but didn't so will be having a look at the fuse tomorrow. And possibly control unit...

As I get older I think a lot about the hereafter - I go into a room and then wonder what I'm here after.

Re: C5 X7 Pollen Filter Replacement & Air System Clean How To
That's why I thought I'd take a pics of those other items whilst there as it may help put things into perspective seeing them in relation to the other parts.
That filter was gross. The fan is running a hell of a lot better now Paul.

Re: C5 X7 Pollen Filter Replacement & Air System Clean How To
That's a very useful guide thank you and the job looks rather more difficult than replacing the filter on the 2006 edition. Currently I let the dealer do the annual service to maintain the Citroen warranty which I have and although the car was on 42000 at the last service, I was told the cabin filter is only changed if it's ordered to be done. That I did at considerable additional cost.

Re: C5 X7 Pollen Filter Replacement & Air System Clean How To
Thanks for that info John, i'll have to dig out some of my old service invoices to see if it was done and if so when. To be honest the job wasn't that difficult when you're not taking pictures and fiddling about with things. It can be a bit difficult withdrawing the filter and putting it back in but generally the trim is dead simple to take out on the passenger side so quite an easy job. Now I've done it once it should be even quicker next time round as I know what I'm doing. I really was surprised at how dirty and how much rubbish is inside that filter, and when you consider that's what's filtering out the air you breathe in the cabin it was quite disgusting. So I will certainly be changing it at least once a year from now on myself.

Re: C5 X7 Pollen Filter Replacement & Air System Clean How To
I just checked - last service was a Citroen 'Essentials' fixed price service and that was for Oil Filter, Plug, Air Filter, Diesel Filter & Oil and a Body inspection, Total £234.95 inc. VAT! Again that was for warranty, so now that is coming to an end, I think I'll be doing most of that.

Re: C5 X7 Pollen Filter Replacement & Air System Clean How To
That is expensive, maybe £50 worth of parts and £200 for 20 mins labour. I hope you got at least £300 out of the warranty.
