Firstly, let me say that finding battery drains on modern cars can be very time consuming. Many cars can take around 40 mins for everything to shut down. So ,my question is, what is the battery drain after this time scale? Pulling fuses is not the way forward to locating a battery drain .It doesn't work on a can bus network. Every time you pull and refit a fuse, the can system will be woken up. Is the car fitted with soft closing doors? Get yourself an Amp Hound . this will help isolate the problem.
