audi a4 - hot air

[dxc...@hotmail.com]

I've got a 2002 audi a4 3.0 and for the past few weeks, no matter what
the temperature setting is on its climate control system, its only
blosing hot air. Someone told me it might be the pollen filter. If
so, what does this filter do, is it needed, and how often and easy is
it to replace? Also does anyone have any idea how much the filter
costs, and does it matter if I purchase an after-market or do I have to
go through Audi?

Thanks much

Dave

I'm pretty sure this is the same as the "cabin filter" I see on
thepartsbin.com
It filters the air coming into your cabin of the nasty stuff you don't
want inside your car with you. I have no idea if it would actually
cause the climate control to stop functioning like that, but it's
worth a shot. Besides, they say "Recommended replacement is every
12,000 to 15,000 miles, or once a year."
If it's the same as other Audi's and VW's I've had, it's probably
under the rain tray at the base of your windshield. Not horribly
difficult to do, but a bit time consuming.
I'm seeing $25-30 as the price, and I would recommend going with the
Bosch or Mann part if it's less expensive than the dealership's price.
That's probably what they'd sell you anyway, just with a nice markup.
Hope that helps,
- Justin
