Peugeot 3008 48V Hybrid 48V Battery Crash Data Reset

Specialist Postal Repair Service

Why Does My Peugeot 3008 48V Battery Lock After a Collision?

Modern Peugeot 3008 models fitted with the Hybrid 48V mild-hybrid system store crash event data inside the 48V battery's Battery Management System (BMS) as a safety measure — even after minor collisions, or sometimes low-speed bumps that trigger the sensor. Once this crash flag is written, the 48V system locks out and cannot be re-armed by standard diagnostic tools, since the crash record is held in a protected memory area. This typically triggers fault codes such as P0AE3, P1AF0, disables mild-hybrid start-stop assistance, and can prevent a clean MOT pass.

Can the 48V Battery Be Reset Without Replacement?

Yes — in the large majority of cases, the 48V battery itself is undamaged; only the BMS crash flag needs to be professionally cleared. Replacing the entire 48V battery at a dealership can cost significantly more than a reset service, and is often unnecessary once the crash data has been properly addressed.
