A few weeks ago, my Indy informed me that a broken thermostat was the cause of my “service engine soon” indicator. I did it myself, not paying him $400 to do it.
After around 10 minutes of operation, the engine light turned on. However, the light turned back on after a restart. When I arrived home, I searched on YouTube and discovered a footage of a man using just the odometer button and no tools at all to reset his 3 series service lights. I tried it out of desperation, and it worked!
I’ve previously used that button to reset other things, but I had no idea you could also reset the engine light. Hope this was useful.

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.
What causes the check engine light to appear most frequently?
The oxygen sensor is the same way. This important component measures the amount of unburned oxygen present in your car’s exhaust, and if there is too little or too much, it may harm other engine components. Every time an oxygen sensor fails, a check engine light will come on. In fact, it’s among the most frequent causes of a check engine light appearing while you’re operating your car.
Without a scanner, how do you read BMW error codes?
While turning the ignition key ON, press the Trip and Reset buttons on the odometer. Release the odometer Reset and Trip buttons after turning the key to the ON position to see if the Diagnostic Trouble Code, or DTC, shows up on the odometer display.
You’ve generated a diagnostic trouble code without a code scanner if the error code appears. Make a note of each fault code and look up the DTC definitions in your manual.
Why is my engine light on when there doesn’t seem to be a problem?

Will changing the gas cap the check engine light off?
The check engine light can occasionally be set off by a loose or damaged gas cap. The fumes that are emitted are usually the cause of this. Simply take off and reinstall your gas cap. If you start your automobile, the engine light can already be back on.
Does a dreaded oil change set off the check engine light?
It’s an annoying sight. You are aware that you should take your automobile to a repair as soon as possible when the check engine light turns on. These lights may indicate a significant issue or something as straightforward as a loose gas cap. Regardless, figuring out the issue is essential.
An appropriately performed recent oil change is one item that won’t cause a check engine light to come on.
