Audi 48V Battery Crash Data Removal – Symptoms, Fault Codes

Audi 48V Battery Crash Data Removal – Symptoms, Fault Codes & Repair Service

Modern Audi vehicles that use the 48V mild-hybrid system can store crash data after an impact or electrical event. When this happens, the 48V system may shut down, show warnings, or disable hybrid functions. This crash data is locked inside the module and cannot be cleared with normal diagnostic tools.

At The Vehicle Check, we specialise in Audi 48V battery crash data removal, module repair, and fault deletion to restore your car’s safety and performance.

What Is Audi 48V Battery Crash Data?

Audi’s 48V system includes the 48V battery, Battery Management Control Unit (BMCU), DC-DC converter, and hybrid starter-generator.
When a crash is detected, these modules store locked crash data, causing:

  • Warning lights

  • Hybrid system shutdown

  • Reduced performance

  • Start/stop disabled

Proper removal is required for the vehicle to function normally again.

Symptoms of Audi 48V Crash Data

You may experience:

  • 48V system malfunction warning

  • Hybrid system disabled

  • Start/stop not working

  • SRS or airbag light staying on

  • No start or intermittent starting

These symptoms often appear even after repairs, until the crash data is reset correctly.
