I drive a W205 Mercedes, the check engine light came on but there's no visible issue, no change in engine sound either — why could it be throwing a fault?

No, I actually solved the problem, it turned out to be the thermostat, I took it to a mechanic who knew the car from the previous owner, he cleared the fault code, and they said if it throws the fault again we'll replace it then, because sometimes the light comes on even though the part is actually fine, apparently. No need to worry, they said the car won't overheat.

It could be from the small sensors, like the fuel cap isn't seated properly. By the way, if you post in the forum section you might get more responses
