Does anyone know how to change the cabin aircon filter on a 2006 volvo S40 1.8i petrol model? Please explain whether or not it can be changed at home, as I still need to know where it is located. Plea

This is for the 2008 (not 2006) but should help you.

I was a little surprised, but according to my AllData data base, this vehicle does not have a replaceable cabin filter. It is possible they're wrong. Try buying one, quite often they come with instructions. If not, don't buy it. This may sound hit and miss but even the manufacturers change things like this within model years.

if the pump is in the tank (which i think it would be) then you're going to have a tougher time. if you could make an adapter to that the pump sucks the gas through a filter first, then all you would have to do is change  the filter in front of the pump. as for modifying it, idealy, you would need to get an external pump and have a filter in front  of it.....could mount it outside, but either way, you will have to do a bunch of jimmy rigging to try and get it to work... good luck, don't know what else to recommend to you..

It's under the dashboard. First you must dismount the accelerator pedal (!), remove some dashboard plastic on driver side. The filter is somewhere behind the central console.
I think it should be changed every two years. Look into the manual.
The company where you take the car for oil & filter change every year must change also this filter with no additional charges. Of course they charge you for the filter, which is not very exponsive.

Remove drivers side kick panel next to gas pedal.  Remove gas pedal at base (three ten millimeter bolts).  Remove access panel to remove cabin filter.

Under the black plastic cover that hides half the engine department.
You need to remove some torx screws in order to get access underneath to the cabine or aircon filter.

Did you say 2006 Fiesta? Focus? Fusion? Are you changing the engine air filter or the cabin air filter?

is the car on recirculate or fresh air? air from your aircon comes through the bottom of your front windscreen, make sure its clear and free of leaves or anything that can cause blockage to stop it from become damp inside the aircon ducts. if it is definately petrol fumes you may have an exhaust leaking from your engine bay, releasing the fumes into your cabin, that is the most common reason for petrol fumes in your aircon.

owners manual should show location,if not its usually beside your blower motor,either behind your glove box,or under dash by pasangers feet area.
