The Warning: A solid or flashing orange/red light on the SOS button typically indicates the internal backup battery is weak or has failed.
The Component: The battery is housed inside the Autonomous Telematics Box (ATB) or Independent Telematic Unit.
Location: In the Peugeot 2008 (especially 2019+ models), this unit is typically found behind the dashboard, often near the steering column or behind the glovebox. Some variants may house it near the overhead console. 2. Required Tools and Parts
Part: Use only the Peugeot-authorized rechargeable backup battery (specific part numbers vary by model year, so confirm with a Peugeot Specialist). Tools: Cost estimate : Battery ~$10–20, DIY labor 30–60
Plastic trim removal tools (to avoid damaging the dashboard). Socket set (10mm for main battery terminal removal).

Replacing this battery is more complex than a standard car battery change and often requires a "BSi reboot" or diagnostic reset to clear the error.
Safety First: Ensure the ignition is off. It is highly recommended to disconnect the vehicle's main 12V battery negative terminal first to prevent electrical shorts during dash removal.
Access the Unit: Carefully remove the trim panels under the steering column or behind the glovebox to locate the Telematics Box.
