Possible Pollen Replacement

I'm sure the lhd and rhd filters are the same.

There are two versions on the filters.  One (as in mikes pic) is a higher quality version to the other and more of a 'pollution' filter.

Just noticed - the part number in tfsi_mike's photo (1K1819653B) is for a left hand drive filter according to ETKA.

The RHD version part number is: 1K2819653B. This is for the better activated charcoal version of the filter.

I've just found this on ebay, an Audi main dealer in belfast offering the charcoal version for £10 inc. postage! So nearly a fiver cheaper than getting it from your local main dealer! (ETKA price is approx £14.50)

My active charcoal filter was bought in Germany and fit perfectly on my Uk Cupra. 

It may 'fit' - but are you sure the air is flowing over it in the correct direction?

The non-charcoal cheaper filters can be fitted with the airflow in either direction, but these more expensive charcoal ones are supposed to be directional.
