Educational use only

The information provided on BimmerByte is generated by an AI language model from publicly available sources and is intended for educational and informational purposes only. It is not professional advice. Always verify every module, parameter, address, and value against your tool's own interface and against current, authoritative BMW documentation before flashing anything.

Coding is risky

Coding changes can — among other things — disable safety features, trigger persistent warning lights (airbag/SRS/MIL), affect emissions compliance, void portions of your factory warranty, and in worst cases brick a control module. Always back up your existing coding (CAFD/FA backup) before making changes, and never code with a low battery or without a stable supply.

Legal use

Some coding changes — including but not limited to video-in-motion, certain lighting changes, deletes/retrofits, and emissions-related parameters — may be illegal on public roads in your jurisdiction. You are solely responsible for ensuring that any changes you make comply with the laws and regulations applicable to you and to your vehicle.

No liability

BimmerByte and its operators accept no liability for any direct, indirect, incidental, or consequential damages — including but not limited to module failure, towing or repair costs, warranty rejection, fines, or any other loss — arising from use of the information provided. You assume all risk.
