The DTC in the BMW 3 Series model E91 is the road assistance system that activates automatically or can be manually activated by the driver when driving on wet and slippery roads. This system helps the car maintain its trajectory or stay straight.

The system usually activates automatically through sensors located in the front wheels, capable of detecting whether the vehicle is losing traction. The system not only helps prevent skidding but also adjusts the engine power, brakes, and wheels.

If you are unsure whether the road ahead may pose problems, you can manually activate the system by pressing the button located under the triangle on the center dashboard.
