Hi I am trying to change the air filter in my 3 ltr Ducato.I presume you undo the 4 screws at the top of the filter to remove the top end.
These screws are very rusty and mangled and will not undo.
Is there another way of removing the filter before I try to drill out these screws.

Just taken a look at the diagram, its the same housing as my multijet 100, sorry to say that there is no other way to remove the air filter. If you can get a hack saw blade to the screw heads, you could cut the head and use a normal screwdriver to remove the screw.

Remove the filter housing complete. Undo top retain bolt and the bracket underneath holding it on. Remove the inlet and outlet hose connections and lift away.

Thanks people I had to drill out the screws but job now done.
