I mean those sequences of button / pedal presses with doors / bonnet in certain positions to achieve service tasks.

E.g. bonnet + door open, ignition on, both pedals down for 60 seconds to reset the service indicator.
Recirc button reveals cabin filter
Double press of cruise control cancel button reveals actual oil level when it says 'unavailable'
There's one to put the parking brake in service mode.

Is there a definitive and complete list of these things anywhere?

Should we collate one?
