thanks for the replies, I have read my manual and as I wrote it looks complicated. I wanted to skip the filterchange, but according to the servicesheet this must be done every 40K km/ 24month, and mine is past that. I was thinking about taking it to a dealer but there are only 3 NAS'es in Denmark so the Land Rover dealers don't have a great deal of experience with this type. Futhermore Land Rover Denmark charges 150$ /hour for service so I would prefer to avoid that
. Do you guys take your automatic Defenders to the dealer for filterchange , or do you simply drive with the same filter??
