Pollen Filters

[leestudd30]

Do they really need changing? What happens if you don't?

[jasper5]

Yes they do.

You can get nasty smells inside the car or the car can keep misting up if you don't replace it.

They only cost a few quid and are well worth it. The clues in the name filter, they filter out loads of rubbish and keep it from the inside of the car.

Oh right, had no idea, I assumed it literally was for pollen and nowt else! I've seen prices for them, where do I find it on the car and how do I change it?

Yes they're well worth changing and it only take a few minutes......unlike my Volvo one

Good fun those Welly

I've got them down to 15 minutes now.Same as Focus from 2006 on.

That seems to be a fairly good system. You could do it in the rain!

Oh now that's taking the piss

You haven't 'done' a pollen filter until its taken you 40 minutes and given you bruised hips and saw elbows

don't forget that a clogged pollen filter will cause extra load on the blower motor, possibly damaging it with extended use. 406s don't have a great track record with blower motors as it is...

Surprising as it may seem, restricting the inlet flow to a fan reduces the work it's doing & hence the current.
(The downside is it may depend on the airflow to cool the motor).

when i bought my 2nd d8 back in december it never had one in the slot. it had a plastic frame covering it to stop leaves going down inti the fan .

looking at stuff around the fan it looked like its never ever had one either

so i bought one and put it in

I thought making a fan pull against a vacuum would cause slower rotation resulting in higher current draw -> hot coils -> burnt lacquer -> short circuit -> burnt mess?

No - the fan works by moving the air, less air = less work to do. It's not intuitive. I remember removing the inspection covers from a big force ventillated DC motor to check commutation, a few seconds later the fan overload tripped, stopping everything and landing Doggy in hot water.....
Trying to prevent a repeat, I resorted to desperate measures, (the manual), which advised in bold type, "Before removing the inspection covers, blank off the air intake to prevent fan overload trip resulting from the increased airflow"
