Hi, Does the BKD engine have a crank case breather filter on it anywhere that needs replacing ?

If you do a 'find on this page' ctrl-f on this page it'll highlight all the engine diagrams relating to BKD for your year of Octy2: https://skoda.7zap.com/en/cz/octavia/oct/2005-419/1/

Click on any that look like they might detail breather system parts.

 

I can't think of any VW group car with such a thing, but I know hardly anything, especially about diesel engines.

 

Thanks mate,  Just that every car previous to this one which ive owned had a filter of some sort that needed replacing at every service, Those were all petrol engines though.
