On my 2003 jaguar s-type v8 4.2 my cabin filter is on the passener side. all help web sites say it is on the driver side. i am having a hard time buying this filter. it looks like the ones all the parts places have is that for the driver side. is there something special about my jaguar or was there a change or mod to some s-types???

Above the rear axle on the driver side

It is located under the panel in front of windscreen

It may be part of the problem, if the filters are located in the cowl (the part of the car in between the windshield, and the hood) It may be as simple as the cover not being on quite right. May just want to pop the hood and inspect everything along the cowl to make sure it all looks right.

Location of cabin air filter (under hood, passenger side), shown without the filter cover installed.

To change the cabin filter on a s-type you will have to open the bonnet and look to the plastic scuttle panel below the windscreen and wich ever side your steering wheel is it will be the opposite side..

For a rhd vehicle you will want to go to the left corner of the car and remove the first 3 clips that hold the scuttle panel to the brace then there will be 2 blanking plugs above (almost at the top of the panel) remove the 2 T20 sdrews and lift the panel up enought so you can get your hand on the filter door. Lift the flap up then swap your old filter with a new one.

These filters should both be replaced at the same time, every 6000 miles or every other oil change. However, the cabin filter almost always fouls up faster than the engine air filter, so maybe every 3000 miles for the cabin.

Have to first remove the plastic cover under the windshield wipers in order to have access to the cabin air filter. It is held together by plastic expansion plugs and four torx bolt covered by rectangular cover. Then remove the windshield wiper and presto air filter.
