Thanks for the replies. Had a proper go today and it was pretty straightforward: Unclip MAF sensor Loosen circlip on air inlet pipe and pull away from filter housing Unclip 3 rubber hoses that are attached to housing Unscrew Torx screws on housing Wrestle filter and housing lid out of the gap Replace filter Reverse the above to reassemble

Hi all, I recently bought an A4 B9 Avant 190 TDI 2017 and would like to replace the air filter as it has never been changed and will not be for another 40k miles if I follow Audi's service schedule. (The pic above is from the web but shows the same engine bay as my car) I had a quick look at how to get at the filter the other day. I removed the housing lid torx screws easily enough but then couldn't remove the lid and filter easily due to the various hoses and pipes which attach to it / run accross it. Has anybody changed one of these and can advise on the proceedure before I get heavy handed with it and break something?! Is it a matter of disconnecting the sensor/intake/hoses or do I just need to pull the lid and filter harder? I have an OEM filter ready to fit and the old one looked pretty filthy from what I could see when I had a poke about. Thanks in advance. Marc
