Удаление катализатора: почему решение оказалось не таким очевидным.

During a routine clutch replacement, the front catalytic converter (catalytic converter) was unexpectedly found to be failing. The solution seemed obvious: remove both catalytic converters, install a flame arrester, reprogram the ECU, or install a decoy. But is this really the best option? This video shows the full diagnostic process: catalytic converter endoscopy, engine cylinder inspection, searching for the possible cause of the failure, and analyzing repair options. After the repair, the car was driven for some time with the diagnostics running, allowing us to evaluate the effectiveness and correctness of the decision. This video is not a guide on catalytic converter removal or a call to action. It is an example of how technical decisions can be made not out of habit or common advice, but based on diagnostics and analysis of a specific situation.
