First, thanks to 1move, akula-ssh and marko-tomas13 for answering my last post. Now I would like to know, how often it has to be change. It did not tell from the owners manual.

 

The maintenance schedule calls for a change of every 30,000km.

 

The only thing with this is that if you drive a lot on dusty country roads or you see the filter getting clogged up a little sooner then its worth changing it. It isn't expensive and its a quick 5 min job so I say change it when it gets clogged, that will depend a lot on how much and where you drive.

 

I air compress/dust off mine once in a while and replace it every 50000km's

 

The dealership charged me $120 to change my cabin filter. Can someone send me the instructions to change the filter for my B6?

 

Here's my audizine DIY:

IMO needs to be done more than every 50,000 km, esp if you have the activated carbon type.

 

marcj just posted a great DIY above that, it may be a little different depending on your model but the general location and procedure is similar.

 

holy ****, 120. DAM it took me less then 5 min to do mine

 

Thanks for the DIY. I had the filter changed the day after I bought the car...I'm a lot more educated on servicing my Audi. I found a great mechanic, and knowledgeable communities such Audiforum have been a great help.

 

anybody know how to change the filter for a 2006 A6 Avant? must be in inside behind glovebox. How do you remove that without breaking all the plastic ^%$&$.
