The check engine light, also known as the Engine Management Light (EML), is a dashboard warning sign for BMWs. It will turn on if more serious problems are found in the components or systems of your car that interact with the engine and the exhaust systems that link to it.
The main computer in your BMW, also referred to as the ECU or Engine Control Unit, is directly connected to the engine management light. The check engine light and an error code will turn on if the ECU notices a problem in one of the aforementioned systems. This can be used to appropriately identify the issue and fix it.
Depending on how serious the problem is, a driver must decide how to react right away to the EML. If the vehicle still seems to be in good working order, reduce your speed and head straight for a shop that specializes in repairs. However, pull over and request a rescue truck to tow you to a repair facility if the EML flashes red or if your automobile no longer feels safe.

We apologise for the eight-month break in Project E46 M3 updates, but despite having a problem during the previous year that we kept quiet about, the car is currently functioning great. A new performance item has even been dyno tested, and several stylish exterior and interior changes have been made, but we’ll have more to say about that soon. We’ll talk about the aforementioned problem we resolved today.
If your BMW E46 hasn’t yet displayed the yellow “EML” indicator, it won’t be long. Its name, Elektronische Motorleistungsregelung, can refer to a wide range of “electronic engine power control” problems, most of which are connected to the drive-by-wire technology.
Ah, I see. the delightful EML light. In the instance of Project M3, when this light would turn on, the vehicle would immediately turn off and would not start again. As if we had a dead ECU, the engine would start to run but there would be no fuel or ignition. Not enjoyable if you’re unsure of what to do.
Yes, that is the low windshield fluid indication, which is empty (due to an error I made when installing a splitter I’ll soon be discussing with you). Yes, the airbag light is also on there, which has appeared on each of the five M3s I’ve owned. I just don’t care about it anymore since I’m so accustomed to seeing it.
Throttle Position Sensors (TPS) are the most frequent component to fail in the EML circuit, and the #1 TPS, which is located just above the air filter, is the one you want to have a problem. Simply put, replacing it is the simplest.
Before the AEM Infinity EMS installation, soon after we swapped our Corsa exhaust and VAC Motorsport pulleys, I first experienced the EML light turning on. It was first perplexing because after replacing TPS #1, the car ran smoothly, only for the light to return a week or two later.
Be careful not to strip the weak-sauce Phillips screws when replacing the TPS. Later, I changed them out for these Allen-head, socket-head cap screws with a size of M4 0.7 x 25mm.
Sadly, after a few weeks the EML light would occasionally turn on and the car would stall once more. I had hoped the latest AEM Infinity installation in Part 6 would resolve this, but sadly, nothing changed. But after that, it continued to drive well for several months. So strange so far.
I didn’t figure it out, or so I thought, until my wife and I drove from Kansas City to St. Louis in November 2013 to watch Argentina play Bosnia/Herzegovina in a FIFA soccer friendly (oh cow there are a lot of Bosnians in St. Louis!). At first, I had assumed that we were permanently stranded by the side of the road and that our weekend was over. Fortunately, we both discovered—well, she did, and she wants my readers to know about—that removing fuse #29 and reinstalling it with the key off turned off the EML light. (I just recently noticed that removing TPS #1 and plugging it back in would accomplish the same feat.) This method would be effective, but only for around 20 minutes.
Suitable Services
The electronic throttle control system is referred to as EML. It is a system that is built into the engine and body controllers that chooses the ideal throttle position depending on the driver’s demands. The light turns on if a malfunction is found in any of the several sensors and actuators that are in use. You are probably not in immediate danger of being stranded because redundant parts like throttle position sensors and accelerator position sensors are installed, but you should have it checked out as soon as possible. To discover what needs to be done, a technician can plug into the diagnostic port and read the stored information. You can have a technician from Your Mechanic visit your house or place of business to read your car’s codes and inform you of what needs to be done.

My BMW EML light is on, why?
This sign represents a DME or DDE issue (ECU – engine control unit). Known as an EML warning light, this is. Electronic Motor Load regulation is referred to by the abbreviation EML. Keep in mind that you will see this lamp if your ECU identifies any issue with the engine’s operation.
What is a BMW EML reset?
Turning the ignition on and off is an even easier approach to switch off the engine management light. The result of this method is the same as the previous one’s, except the battery is not disconnected.
What exactly does EML on my dashboard mean?
It can be unsettling when the engine management light comes on, but what does it actually mean, how serious is it, and what can you do to fix it?
The engine management light, commonly known as the “check engine light,” is a dashboard indicator that turns on when there is a problem with your car’s engine, exhaust, or emissions system. The EML is a general warning that something is wrong with your car rather than a specific issue like a “low coolant” or “check oil level” message or light would be.
When the EML light is on, can I drive?
Generally speaking, you can keep driving to your destination unless there are more signs that something is amiss. To prevent further harm to your car, you should then have it inspected by a professional as soon as you can.
However, if you notice further problems with your car that point to an issue with the engine or if the EML is red or flashing while the engine is running, this may be a sign of a more serious issue. If this occurs, you ought to:
- As soon as it’s safe to do so, stop.
- Turn off the car’s engine.
Can I operate a BMW with the check engine light on?
A constant glow normally denotes something less serious, but a check engine light that flashes suggests your car’s engine is seriously damaged and needs quick repair. We strongly advise not operating your BMW while the check engine light is flashing and setting up BMW servicing right away.
Will a BMW check engine light automatically reset?
Since the Condition-Based Servicing system is used by the majority of BMW models, your check engine light ought to automatically turn off after the problematic issue has been fixed.
Does an oil change cause the BMW check engine light to turn on?
- Needs Oil Changes: When it is time for an oil change, your BMW service engine light will on. The goal is to inform you when the time and mileage limits for your current oil have been reached. If you keep using your engine without changing the oil, even the best repair shop won’t be able to fix it.
- Low Oil or Other Fluid Levels: The service engine light also warns of low transmission fluid, coolant, or oil levels. Due to these low levels, this safety feature works to protect your car’s components.
- Regular Scheduled Maintenance: The computer in your BMW is preprogrammed with the timings for your regularly scheduled maintenance. The service engine soon light signals that your car needs to be taken in for its scheduled maintenance.
Your BMW will live longer and retain its value if you have routine maintenance done on it. You will eventually harm your car’s engine and other parts if you neglect any regular maintenance.
With the right preventive maintenance, a well-built car like a BMW can last for hundreds of thousands of kilometres. If your service engine light turns on, consider it a chance to save money and ensure you have a dependable car to drive for many years.
Does the engine light signal low oil?
There are a number of things you may do immediately if your check engine light illuminates to determine whether there is a problem. By looking into these, you may be able to find a quick solution, quickly spot a wider issue, or, at the very least, swiftly rule out some of the potential problems. As soon as the check engine light illuminates, the following issues need to be addressed:
- Your engine’s missing its cap: If fluids is exposed, your check engine light can come on.
- Unplugging or having a loose wire can cause a check engine light to be activated very rapidly. A wire can also become loose on its own or be damaged by an outside agent, like a mouse or squirrel.
- Low oil pressure: Your check engine light can come on if your automobile is low on oil. This is frequently displayed in its own bright light in addition to the dashboard check engine light.
- Overheating: The check engine light may once more come on if your car’s engine temperature is rising. Stop immediately if you notice the temperature indicator rising.
Some of these problems can be easily fixed by the homeowner, including by adding more oil or changing a cap. However, you might need to take your automobile to the repair if it’s overheating or if a mouse chewed through an internal wiring.
Some models will have a yellow version of the light to suggest that you check for problems and a red one to signify that you should stop right away, according to the system. However, regardless of the precise hue of the signal you see, you should always pull over as soon as you can if you aren’t convinced that this is the case.
In any case, if your check engine light comes on when your car breaks down, it’s critical that you carefully analyze the situation, refrain from performing impromptu repairs, and stay safe until you have your car towed to a shop where it can be properly assessed.
My engine warning light won’t go out.
- As you drive, let the light turn off on its own. None.
- Three consecutive times of starting and stopping the engine None.
- Reconnect the battery after disconnecting it. Wrench.
- Use a code reader for the OBD
What is the cost of fixing the engine warning light?
Over the past year, the average cost to correct a “check engine light”-related issue dropped by 10%, and it now costs 15% less than it did in 2006. The current national average repair cost for a vehicle’s check engine light is $357, which includes labor ($141) and parts ($216).
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.
