BPGA is a French abbreviation for "Boitier de Protection et de Gestion de L'Alimentation" - The English translation is : Power Supply Protection and Management Box. Some people call it the battery protection unit.

My understanding is that it's a safety device and one of its functions is to cut power in an accident. It also helps to save battery power by disconnecting the power to several devices a short time after the engine has stopped.

So now I know what puts my car into Eco mode and shuts the radio down when waiting for my wife ! Think I will call it the pain in the bottom unit .

All Peugeots even those without a BPGA have the Economy Mode function. It does two things -
(i) Disconnects the power to all but essential things if the battery voltage is low.
(ii) Turns off the accessories such as the radio after 30 minutes if the engine is not running..

The only way to clear it is to start the engine.

The BPGA turns the power off to essential things as well and if its relay fails (and they do) the car will not start. It even turns the power off to the OBD connector so some scanners won't work.

Yet another good bit of information to keep, so if your car will not start and your OBD scanner wont work to fault find look at the BPGA relay.

Some OBD scanners use the "permanent" 12V supply on pin 16 of the OBD connector. The Peugeot diagnostics system and other good diagnostic testers don't need it.

Good news as I use diagbox due to running older Citroen and Peugeot models for some time.

You can not disconnect the BPGA but you can bypass it as a temporary measure. There are several versions of the BPGA but this video may help you bypass it -see time 13:23.
