I looked online, but all I could find was information on how to reset the general routine maintenance light.
I’ve gone through a few coils. I go to Autozone or Advance, they tell me which cylinder is firing incorrectly, I replace the coil, and if the code hasn’t been cleared yet, I return to have it cleared. Free.
Usually, I decode the codes at Advance Auto or Autozone. You could reset the device if they permitted us to use it. The tool is incredibly self-explanatory on its own.
Because it’s a liability for them, Advance and other stores will occasionally be difficult with you about resetting an active light or code. In the event that your car breaks down and they are to blame, it could lead to legal action.
To read and erase codes, either get a cheap code reader/scanner or spend money on a Bavtool, which will undoubtedly pay for itself over time.

What takes place when a car’s codes are cleared?
It’s crucial that technicians don’t clear codes without performing repairs because every dashboard light is a sign that something is broken. They ought to record the problem and then make the required corrections to get the code to work correctly. You can tell that a car has been repaired and is now in good functioning order when a code clears. There might be times, though, when manually removing the codes is part of the repair procedure.
For instance, if the gas cap isn’t properly tightened, the check engine light may come on. However, correctly tightening the cap doesn’t always resolve the issue, and it frequently takes 10–20 cycles before the computer recognizes that the issue has been resolved. In this case, you can remove the code so that the computer can continue to accurately read other flaws and errors without requiring you to retrain your driving habits.

Does my BMW require reprogramming after a battery change?
Let’s first focus on what BMW battery registration genuinely is before delving into the procedure. Battery registration, to put it simply, is the process of notifying your car that a brand-new battery has been installed. Importantly, it must be done every time you replace the battery in your BMW, model year 2002 or later.
The car adapts the amount of energy required to recharge to operate at peak levels as your battery ages and gradually loses its ability to charge. The battery needs more charging the older it is. By registering your battery, you can inform your engine control module (also referred to as DME — Digital Motor Electronics) that a new one has been installed. As a result, the vehicle will reset the old battery statistics and won’t attempt to overcharge the new battery under the assumption that the old one is still in place.
In addition to registering, you must also code your BMW computer. No matter how different or similar your new battery is from your previous one in terms of specifications, it will still be necessary each time you change it.

You can easily determine the mileage of the car by taking into account all of these parameters.
Why is my check engine light still on even if the issue has been resolved?
The light remaining on even after the repair is a concern for many automobile owners. Don’t freak out if you’re having this experience. After the repair, you might believe there is still a problem with the car, but it is only because the light needs some time to reset.
The internal computer of the car only resets after a predetermined interval during which it rechecks all of its sensors. After around 10 to 20 cycles, the reset may occur automatically.
