Lane Assist is a great safety feature, but the Audi A3 8Y defaults to having it "Off" every time you restart the car due to regulations in some countries. You can code the system to remember your last preference. If you like Lane Assist always on, coding can make it stay on permanently until you turn it off.

The Audi A3 8Y is a masterpiece of engineering, but it is often held back by corporate policy and safety bureaucracy. Coding allows you to strip away those limitations and tailor the car to your specific lifestyle. Whether it’s the subtle satisfaction of a needle sweep or the utility of Video in Motion, spending an afternoon with an OBD dongle is one of the best value modifications you can make.
