The way these cars work is the light switch sends a command to the Body Systems Interface which then sends voltage to the bulbs.
the light switch isn't actually connected to the bulbs.
So if I were doing this the first thing I'd do is scan the BSI for any stored faults.
You really need Peugeots diagnostics for this.
Other diagnostic can give false readings.
