The pollen filter is an item which most garages neglect from what i've read!
I decided to have a look at mine the other day. The pictures speak for themselves
I originally thought that the dirty pollen filter might be Carbon Activated, as those are a black colour. But I can't seem to find any for sale. So I think it's just a disgusting old one
Erm, it does if yours isn't a carbon one? Mine was a plain paper filter, old one was black, new one was white. Colour told me a lot
It's amazing how many people don't want their pollen filter changing during a service at work, most are still on the originals and clogged right up. Some are an utter pain to change though, mine isn't too bad, need to take the glove box out and you need a 5.5mm socket.
Mk2 Focus' aren't as nice, need to drop the fuse box and the fuse box bracket under the glove box!
did the pollen filter on the E36 today... it was manufacturered in 2001!!!!!! totally blocked
