Expert in identifying hidden issues in engines, transmissions, and electronic systems. Author of over 100 diagnostic solution cases shared on forums and technical platforms.
I always say: the scanner shows a code, not the problem. My job is to find the root cause — not just clear the error from the dashboard. If something is lagging, acting weird, or just not like it used to be — I’ll figure it out.

How to Choose Oil Additives to Reduce Oil Consumption
18.01.2024The issue of excessive oil consumption concerns many car owners. In some cases, increased oil use is due to technical characteristics of the engine. For example, the first generation of 2.0-liter TSI CAWA engines from Germany’s VAG group could consume up to 500 grams of oil per 1,000 km. However, in most other cases, the problem can be fully or at least partially resolved. Leading automotive chemical manufacturers offer a solution — special additives that improve oil properties and help reduce consumption. Avto.pro explains what these additives are and whether they’re worth using.
How to Check a Car’s ABS Sensor
18.01.2024Almost all modern vehicles are equipped with an anti-lock braking system (ABS). The ABS sensor is an electronic device that measures the wheel’s rotational speed and sends this data to the ABS control unit to help prevent wheel lock-up during braking. It works in tandem with the vehicle’s onboard electronics and braking system. The ABS system includes a set of sensors, which are often the most vulnerable part of the system. In this article, Avto.pro will explain the different types of ABS sensors, the signs of failure, how to test a sensor, and how to choose a replacement if needed.
