Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Vehicles with energy management systems (IBS, power module): Register battery replacement
The vehicle electrical system is informed about the vehicle battery characteristic data, such as type, size, age and current power capacity. Therefore, there will always be only one work scope provided that is permitted by the current status of information.
When installing a new vehicle battery, the battery must be registered and thus must also be registered with the vehicle electrical system.
Diagnosis system:

- Service functions
- Body
- Voltage supply
- Register battery replacement
When retrofitting, a more powerful battery may be used. Standard batteries may always be replaced by AGM batteries with the same specifications.
When installing a battery of a different size or a different battery type, this change in vehicle data must be programmed into the vehicle data in accordance with specifications.
