My Peugeot 307 battery drains consistently
This is called 'Parasitic Draw' and is notoriously difficult to find. This is how you check it.
Fully charge the battery. Put an Ammeter on the positive terminal of the battery. Have someone watch the meter as another person pulls each fuse one at a time. When one or more fuses are pulled, the amperage load with drop considerably. That just highlights which component and which circuit is causing it?
Or take it to a local auto-electrician who has the experience and the $5,0000 scan tool computer.
It appears to be a well known issue on the 307!!

the volume in the passenger compartment. The alarm is triggered if anyone breaks a window, enters the passenger compartment or moves inside the vehicle. Self-protection function The system checks for the putting out of service of its components.

Peugeot fuel, rev, and speed dials not working
Those sorts of issues you can't fix yourself. Look locally for a good auto-electrician. You need someone with a $2,500 scan tool computer than can analyze the electrical system in real time as it happens and record it all.
Look at the Scotty Kilmer YouTube channel for the sort of data a scan tool can diagnose. He recently did a 2006 Lexus.
