What Are Car Coding? What Is It For?


Car coding is a relatively new thing in the automotive world, and it implies software modifications to a vehicle to allow the use of functions not available in the car when it left the factory for different reasons, mainly local regulations. Coding does not imply changing the software! It only changes existing parameters already present in various modules.

A car is a complex machine with many functions that are controlled by a computer. Today, cars are equipped with assistance systems, hands-free options, and other smart services. However, not all of these embedded functions are enabled (or activated) by the manufacturer.

What can car coding bring for vehicles?

Most vehicles have market-specific settings for their features. Furthermore, most vehicles have limitations and other restrictions. With the help of coding by professional car coding tools, a user can change the chimes on their car, set how many times its one-touch signal flickers for one touch, remember settings for Start/Stop systems, and more. Coders can also activate cornering headlights with fog lights, deactivate some buzzing sounds, and enable multiple functions of the comfort module. 

Other possibilities involve lowering the level of the passenger-side mirror when reversing, activate the “needle sweep” function when the ignition is on (only for some Volkswagen AG models), automatic door locking at a particular speed, U.S.-style daytime running lights, the auto-hold function for vehicles with electrically operated parking brake, and others.
