i've been looking at similar issue on another car.
at least d22's are pretty simple. there is not much that draws power with key off. radio and the NATS system (model depending). i would check things like door switches, make sure they work. central locking works.

otherwise measure volt drop across the fuses to narrow it down.

I have the same issue, did you find the problem?

are you running any after market electrical accessories ? What is the voltage of the battery with vehicle turned off ? What is the voltage of the battery with the vehicle running ?

I had a similar issue with mine. It was the alternator. Leaky diode was the issue, I replaced the alternator and now the battery lasts a long time between starts.
