So-called Convenience coding are possible for vehicles from almost all manufacturers / vehicle types. Newer vehicles in particular can be customized and set with a large number of convenience codes. In principle, however, this is also possible with older vehicles. Example: an old Opel Vectra B 1.6 16V from 1996. Using convenience coding, for example, it is possible to open the windows automatically by “holding down” the lock button on the vehicle key closed will. And if you turn them around, you can “hold down” the button to unlock them again öffnen. This function is ex works on this vehicle should not activated for the customer, but can be activated using convenience coding.

the possibilities are endless

Another example: For a VW Phaeton built in 2010 with a factory-installed alarm system, it is possible, among other things, to have a acoustic acknowledgment activate when locking and unlocking. This is a comfort code for the vehicle and its use is not provided in Germanyas prohibited by law. In other countries, however, acoustic acknowledgment is permitted and can therefore be coded in the respective country - under your own responsibility - to be activated. The two examples based on VW and Opel can be continued indefinitely. Even older vehicles from the early 90s have a multitude of functions here. However, current vehicles with digital displays, cameras, etc. clearly surpass the functions of that time. There is almost nothing that cannot be somehow changed or adapted using comfort coding.

Tip: Before you get into the software of the vehicle, you should inquire whether the coding might lead to the loss of warranty claims against the car manufacturer. Coding can affect the essential properties of the vehicle. If these are changed, an obligation to notify / approval by the Federal Motor Transport Authority may be necessary. In the event of violations, there is a risk of fines, coercive measures and even shutdown.

Suitable devices & connection for the comfort coding?

There are lots of tools / solutions available directly from the vehicle manufacturer, but these are usually for the end user should not are accessible. But there is also an extensive range available from third-party providers. Solutions that we have already tested, such as VCDS, Carly, OBDeleven, BimmerCode, Carista & Co. enable the desired coding, depending on the manufacturer and vehicle type. The devices are usually connected via the OBD connection in the vehicle. The connection is usually made via Bluetooth and sometimes over Cables. Special knowledge is usually required not necessaryso that even laypeople can do this type of coding.

However, you should always concernsthat a lot of damage can be done with it, which may only be repaired in a specialist workshop or even result in a repair. Coding always means an intervention in the configuration of the on-board computer. We therefore recommend going to a specialist workshop or a trusted tuner. Simple codings can often be carried out there for a “ten” in the coffee box. Multiple codings or particularly profound changes can also cost a lot more. It always depends on the possibilities, the vehicle and personal wishes. Anyone who is uncomfortable with this, who is unsure or is afraid of consequential damage, should keep away from coding.

Well-known devices for coding!

The following list shows a few examples of common vehicle types and corresponding devices. Many devices can also be combined with several vehicle types / manufacturers. And there are often tools that are suitable for almost all common vehicle brands. In terms of functionality, you have to make compromises from time to time, but when it comes to a few customizations, a universal OBD tool is usually sufficient.

At the end... A vehicle is a complex machine with innumerable functions. These are controlled by one (or more) computers. But not all functions are activated by the manufacturer. Some are even annoying. The functions can be activated, customized or deactivated by coding. Many functions that have not been activated by the manufacturer can therefore already be built into the vehicle. If you want to use them, the car owner can in many cases change the coding do it yourself. At the very end of the post you will find a few instructions for different vehicles!
