Pollen Filter

A got a Service Kit for my TD4, all the filters and gubbins for a service, but no clue where the Pollen filter is located, As I have got it I thought I would replace it, but cannot see where its fitted!!!

Any one know!!

Its in the passenger footwell - the black plastic heater box under the dash, just unscrew the end plate and the filter slides out.

use a mirror in the passenger footwell looking up, makes life easier

4 screws to remove. Have a feel inside for leaves too. I found some in mine.

As the four bolts that hold the cover on are recessed, I found that I had to grind a socket down as the socket walls were too thick to fit in the recess.

I'm surprised you never noticed it before, it's hard not to! Many of my passengers have wondered why there's a big black box down there. (What a stupid place to put it!)

i would add that it is useful to try fitting your old filter back in after you have taken it out, this way you see the angle it goes in at, i nearly snapped my new filter in half bending it into the housing.

Ok- Thanks Job done, nice short cross head Driver needed to remove screws. Not a lot of space to get filter in and out!! but managed, given state of filter, not been changed often!!! Worse than my Hoover!! Sweet fresh air now

Can anyone say what size the bolt heads are on the pollen filter?

I have bolts on mine, not screws.

little ones

Thank You.
Very helpful!

i do try..

if its the little ones i suspect they are sometimes 5.5mm heads

but you could always just get yer feckin socket set out and try?

Very trying!

Just found on another board that the bolts should be 6mm.

I can recall when I first got the car, that I grinded down a socket to fit in the plastic housing but can't for the life of me find it.

one's on mine are 6mm

if y'don't find the ground-down socket
a small rubber grommet under each one works fine
leaves the screw/bolt head slightly proud .. easy to get a socket/spanner on ..

btw: this place does an alternative pollen filter

I managed to find it once I knew the socket size, but that's a good idea.

Now I just have to work out which way round the filter goes as I removed mine about 2 years ago and cut of the cover and just replaced that.

Normally flow arrows on pollen filters

I came to the conclusion my model didnt have a pollen filter after searching high and low. I will have another look now!

i just remember it as the plastic-frame bit on the filter .. faces to the outside of the vehicle .. i.e. to the left
( just replaced mine a few days ago )

I remember an old thread saying some did not have them , also sometimes it is good to own a quarter inch drive set it saves grinding down sockets

L-series with AC have no pollen filter fitted.
