# What can be coded on VW, Škoda and Audi _Updated: 8 November 2026_ **Short answer:** On VW, Škoda and Audi, coding turns on features the car already has but the factory switched off. The most common are mirrors that fold by themselves, closing the windows with the remote, coming-home lights, a fog light that comes on when you turn and needles that sweep to the end when you start the car. What exactly is possible depends on the model, year and equipment. > **The service we recommend: Coding** We turn on features your car already has. We tell you the price when you tell us the model. [More about the service](https://autoindustrija.rs/en/services/car-coding) ## Coding turns on what the factory switched off Every computer in the car has settings that decide what the car does. The factory leaves some of them switched off, even though the car has the part for that feature. Coding is how we switch them on. We connect our computer by cable to the car's OBD port, the same one diagnostics connects to. We do not remove any parts for coding. On cars from model year 2015 on, we open the bonnet before we start, because an open bonnet switches off the protection that otherwise blocks changes in the computers. ## Features turned on most often ### Mirrors, windows and seat - **The mirrors fold by themselves when you lock the car:** The car must have mirrors that fold at the press of a button. On the Golf 6, older and newer cars have a different computer in the doors, so this feature is turned on in a different way on each. - **The right mirror dips in reverse:** You see the kerb while parking. Turn the knob you use to adjust the mirrors to the right mirror, marked R. On the Golf 7, after coding, also switch the feature on in the screen menu. - **The windows close with the remote:** Hold the lock button on the key for about 3 seconds. First the car locks, then the windows start to close. Then let go of the button, and the windows close all the way by themselves. If the car has a sunroof, it closes too. - **The windows work after switching off:** When you switch the car off and open the door, you can still raise or lower the windows. - **The mirrors heat with the rear window:** Switch on the rear window heater and the mirrors heat by themselves. You do not have to turn the mirror knob. - **The seat moves back when you get out:** When you switch the car off and open the door, the seat moves back, so getting out is easier. The car must have an electric seat. ### Lights and wipers - **Coming-home lights switch on by themselves:** When you get out in the dark, the headlights stay on for a while after the door closes. You do not have to pull the light stalk. - **The fog light comes on when you turn:** At low speed the fog light on the side you are turning to comes on. This helps in a narrow street and at a roundabout. The car must have front fog lights. - **The lights flash when you brake hard:** On the Golf 7 the indicators flash, and on the Passat B6 the brake lights. - **The rear wiper works with the front wipers:** When you switch on the front wipers, the rear wiper starts wiping by itself. ### Dashboard, sound and phone - **The needles sweep to the end at start-up:** When you start the car, the needles on the dashboard sweep to the end and back. On the Golf 6 this works on cars from the end of 2009, and on the Golf 7.5 also on the digital dashboard. - **Oil temperature on the dashboard:** The oil temperature shows on the dashboard screen. On the Audi A4 B8 it appears next to the stopwatch. - **Battery charge on the dashboard:** On the Golf 7, switch the car off and hold the trip reset button. The dashboard first resets the trip to zero, then shows the clock setting, then the battery. Then let go of the button and the dashboard shows for a few seconds how full the battery is. - **A sound when you lock the car:** The car gives a sound when you lock and unlock it, so you know it is locked. On the Golf 7 it is also switched on in the screen menu after coding. - **Two phones at the same time:** You connect two phones to the car's screen over Bluetooth at once. - **Wireless CarPlay and Android Auto on the Golf 8:** The phone connects to the screen without a cable. The car must already have CarPlay over a cable. ### Driving - **Start-stop stays off:** The engine no longer switches off by itself when you stop. Not possible on every car: on some Golf 7 cars from 2019 this change no longer works. ## What is possible on which model The same model does not have the same options in every year and trim. That is why, before we start, we read your car's computers and see what it really has. ### Golf 6, Octavia 2 and Passat B6 On these cars we turn on coming-home lights, the fog light when turning, closing the windows with the remote and flashing lights when braking hard. A lot depends on the year. On the Golf 6, coming-home lights are coded differently on cars from before and after the end of 2009. On the Passat B6, the fog light when turning is not possible with every version of the computer. ### Golf 7, Octavia 3, Superb 3, Audi A3 and SEAT Leon 3 These cars from the same years are built on the same base. On all of them we turn on mirror folding, coming-home lights, the fog light when turning and the sound when locking. On them we also code the car after a reversing camera or a tow bar is fitted. ### Audi A4 B8 On the Audi A4 B8 we turn on the needle sweep at start-up, mirror folding with a setting in the screen menu, the right mirror dipping in reverse, the fog light when turning and the oil temperature on the dashboard. ## Golf 8, Octavia 4 and the newer Audi A3: the computers are locked On some cars from model year 2020 on, the computers are locked. Reading fault codes works as before, but before coding the computer has to be unlocked. We unlock it online, and only then do we code it. On the Golf 8 this is the case, for example, for wireless CarPlay and for registering a new battery. Some computers in the newest cars have even stronger protection. On them, a feature the car did not have from the factory mostly cannot be turned on, especially driver assistance systems. We'll tell you what your car can have when you send the make, model and year. ## No part in the car, no feature Coding does not add a part the car does not have, a camera for example. For such a feature the part is fitted first, and then we code the car to recognise it. After a reversing camera is fitted, the screen shows the picture only once we code the car. The same goes for a new USB port for CarPlay. After a tow bar is fitted on a Golf 7, up to 12 settings change in several computers, and after front fog lights are fitted, 15.

The details of that exact battery are entered into the computer: capacity, type and maker. Without it, start-stop may stop working and the car uses more fuel.

Coding changes settings in the car's computers, but it does not change engine power. ## What the price of coding depends on There is no single price, because every model and every feature means different work. **The coding price depends on this** - How many features we turn on. - How much work each feature takes. The needle sweep on a Golf 7 takes one change, and mirror folding 5. - Whether the computer is locked, as on some cars from 2020 on. - Whether coding goes with fitting a part or a new battery. We'll tell you the price when you send the make, model, year and the features you want. ## Frequently asked questions ### My OBD port is relocated. Can you still code the car? Yes. Bring the adapter you got with the relocation. With the adapter in the hidden socket, we connect our computer to the factory port as before. If you have lost the adapter, contact us before the appointment. Have a question about your car?
