The need for engine diagnostics, which the owner performs independently, may arise for various reasons. In some cases, the procedure is performed regularly for preventive purposes, in others, do-it-yourself motor checks allow you to save money and do without visiting a car service, etc.
In any case, it has become easier to determine the breakdown and check the general condition of the internal combustion engine and its systems on a modern car. The fact is that the introduction of electronic control systems with self-diagnostic modes allows the engine ECU to record possible errors, which, after decoding, indicate the cause of the failure or breakdown.
Also, do not forget about proven diagnostic methods, which are based on the analysis of noise, exhaust color and other signs that indirectly or directly indicate a particular problem.
First of all, timely diagnostics allows you to quickly identify possible malfunctions at the initial stage. In other words, it is possible to quickly identify breakdowns even before they develop into serious malfunctions.
Experienced owners are well aware that ignoring minor issues as a result can lead to bigger troubles, to overhaul of the engine, or even to the need to replace the unit with a contract motor.
