F15 40d common problems??

[full13]

Hi all recently bought myself a 2014 40d x5 with around 77k

Already had new timing chain last week Along with swirl flap delete,

Being a new X5 owner I was wondering, is there anything else I should be on the lookout for with these 40d??

I’m Already Dropping my oil changes down to every 5-6k

Front control arms, rear suspension airbags if you have that option. Can’t think of anything 40d specific other than oil change intervals which you seem to have addressed.
