48V Battery Fix Service (w223, W206)

If your W223 or W206 with Mild Hybrid technology equipped with a 48V battery experiences a malfunction, preventing your car from starting, we offer solutions for common faults such as:

• B183304: The 48V on-board electrical system battery has a malfunction with an internal fault.
• B183371: The 48V on-board electrical system battery has a malfunction, and the Actuator is blocked.

Before contacting us, it's essential to read the actual values of each cell in your 48V battery using Xentry Diagnosis. If the voltages are within normal values, we can proceed with our fix. However, if any of the cells are damaged, you may have a hardware failure.

Please note:

The price quoted for this service covers repairing the Tricore Bin file only. You are responsible for managing the connection pinout to the 48V battery board.

If you're unfamiliar with the pinout, we can provide a comprehensive guide at an additional cost.

Feel free to reach out to us for assistance with your 48V battery issues.
