In modern cars, electronics are responsible for monitoring almost all relevant elements. Thanks to it, we are able to perform electronic car diagnostics and learn many facts from the history of the car - including the actual mileage.
In the past, automotive electronics were limited to injection molding and ABS control systems. Along with technological developments, it has begun to add electronic controls and controls to the operation of more and more elements of car equipment, such as the control of lights, suspension or even the diffuser of cabin air. This happened after the popularization of the CAN highway, ie. a system that allows data to be transferred between car components.
Thanks to this invention, new possibilities have opened up in automotive diagnostics. Numerous interconnected sensors analyze a multitude of key data for the current operation of individual systems and their maintenance or repair. For example - the brake controller informs about the number of pressures on the brake pedal, and the airbag controller records critical errors together with the mileage.
Advances in automotive electronics have forced many workshops to purchase new equipment and train employees. In turn, it opened up new possibilities for users to verify the history of the car. In fact, anyone who is interested in a used car is afraid that the meter might "turn it back". The fraud of an unscrupulous seller is usually found out immediately after a detailed inspection of the car by an experienced service technician, and it is not necessary to work in an authorized service center. It must be admitted, however, that in the case of professional "correction" of mileage, ie correction of data contained in the modules, this unfair practice is still difficult to detect.
Checking the actual mileage of a used car is just one of the benefits that a detailed overview of automotive electronics can give. Below are examples of actions that can be performed on the electronics of the most popular car brands. Caution! These are just cumulative examples; the ability to scan the car in detail, depending on the model, and often also on the engine version.

Other Skoda / Volkswagen Car Electronics Options:
Doing car diagnostics with an experienced repairer if the dishonest seller has not changed the parameters of the key modules. We will learn the most history facts from the electronics of French and German cars; Japanese and niche brands (like Saab) have limited room for maneuver.
The increasing complexity of electronics means that in modern cars, especially luxury cars, it is increasingly difficult to return the meter. There are companies that deal with this, correcting the memory of almost all modules. Unfortunately, even salespeople who reduce their mileage with simple methods do not account for the problems, as many buyers do not check the vehicle.
