I am looking at maybe putting together a wee post on general maintenance etc for specifically the tdis, although can include petrol engines aswell. What im looking for is things that people dont normally think of, eg not oil changes etc but for example my old vec i had to clean the Idle air control valve and throttle body etc. SO what is there on the leon that could be included in cleaning? I'll try and make a full post so as everyone can get easy access to it
