What to do when our dashboard says "engine malfunction, repair necessary

Model: (Various brands) Various
Part: Instrument cluster

What should we do when our instrument panel shows the dreaded phrase "engine malfunction, repair necessary"? It is an error that appears on most cars, such as Opel, Vauxhall, Citroen, Peugeot, and some Toyota. The first thing that comes to mind is the emissions system, but what we should actually check first is the battery: about half of these warnings are actually related to a discharged AGM battery. The warning appears along with other lights and then disappears, and the car drives normally, only to reappear at the next restart along with other lights, so we are very worried. Other problems, it is true, can be caused by poor fuel combustion, due to faulty spark plugs or a faulty sensor, but in these cases, with a good scanning tool, it is easy to diagnose the problem, which can also be caused by certain AdBlue issues, but what the YouTuber recommends is always to check the battery first.
