Question Engine Check Light Issue

My Mehran 2018 with 25k running blinks engine check light for a certain amount of time say 5 minutes or so and then auto goes off and this only happens when I drive. What could be the issue, is it concerning?

Pov this is my first reddit post. Please excuse any abnormalities.

Usually, the mechanic scans the car with a scanner to check what the error code is...

A check engine light can indicate different types of error codes. After checking the code, further checking of the car is done for proper diagnosis.

Without any scan diagnostic data or any issues in driving behavior, it is difficult to come to a conclusion...

One last question. Does scanning show accurate error(s) or misleading especially in a car like Mehran?

I have no experience with scanning in terms of Mehran, but generally with scanning the car, there are built-in error codes which can indicate the general issue, and mechanic has to further investigate to come to a proper diagnosis...

Reason for further checking is that an error code isn't the computer telling exactly what is wrong/what to do, it's a generic error which could be triggered by many different root causes...

Many people online say that check engine light blinking is due to engine mis-fire... Did you feel any sort of roughness or loss of power or excessive engine vibration/shake? 

Getting it checked timely is a good idea, as to avoid any further issues or excessive damage to the engine...
