REMOVING THE AIR FILTER

Air filter changing is a very easy task to do on the 5, Just open bonnet and remove butterfly bolts on the top if the airbox. Remove the air filter lid and take out the cylindrical air filter element. Throw the paper filter away and replace with a new one. While you've got the lid off you might as well make sure to clean out air box and check pipework from the box to the turbo intake for leaks.
