The cabin filter in the gen 1 is VERY easy to replace yourself. No tools required! The gen 2 on the other hand is a nightmare from what I've read. It requires a socket wrench and an extender to reach the bolts that secure the hatch cover that holds the filter hostage. If you have the tools and the patience, you can do it yourself, otherwise it might be less hassle to let the dealer do it. Entirely up to you though.
