★ Top Answer
The BMW fault code A3B4 indicates an issue with the MINI footwell module (FRM3), responsible for handling various comfort systems in your BMW, such as power windows, A/C, heating fans, lights, and mirrors. If you encounter this error, you may find certain features not functioning properly, including headlights and taillights. The usual solution involves replacing the module at the dealership, which can be expensive. Alternatively, you could ask them to reprogram it, which might resolve the issue and be more cost-effective in terms of labor compared to a complete replacement.
