Hello, thank you for writing in. Typically the light that illuminates when the engine is limited is the "reduce power light". This light can illuminate for several reasons, and its purpose is to preserve the engine because a fault has been detected. If a warning light of any kind has illuminated, then there is a diagnostic troubleshooting code that has triggered. This happens when a system fails a test which the computer runs constantly. Without knowing the exact year and model it is difficult to say what the issue may be. The best thing to do at this point is have the vehicle scanned for diagnostic codes at a parts store or by a technician.

A steady glow typically means something less serious but a flashing check engine light indicates that your vehicle`s engine is in serious trouble and service is needed immediately. If your check engine light is flashing in your BMW, we highly recommend not to drive the vehicle and schedule BMW service today.
Reasons why a BMW check engine light may turn on
It can be anything from a loose gas cap to an internal engine problem. Other reasons include a circuit problem, the catalyst system working below its threshold, and issues with the coolant system. BMW repair is one of the services that Steve`s Auto Repair & Tire offers.
This can be caused by a number of different things, including a problem with the oxygen sensor, the airflow meter, or the throttle position sensor. Your check engine light may also come on if there is a problem with the acceleration. Engine speed sensors may also be another factor.
BMW Check Engine Light Flashing
Distinctive acknowledged reasons for a Check Engine Light are faulty emissions control part, dirty mass airflow sensor, damaged oxygen sensor, faulty head gasket, a malfunction with the fuel injection system, or defective spark plugs to name a few.
How long can you drive with the check engine light on? Once you see the check engine light, it is safe to drive with the light on for 50 to 100 miles. This is because if the issue is with the sensors, then this will buy some time for it to reset, turning the check engine light off.
Since most BMW models use a Condition-Based Servicing system, your check engine light should reset itself automatically if and when the offending issue has been resolved.
The “check engine” light is the onboard diagnostic system`s way of telling you something`s wrong. But that something could be one of many things, big or small. It could pop on because of something minor like a loose or faulty gas cap. It could also mean a major engine failure.
Typically when the car will not accelerate past 60 MPH, it`s due to either the ECU activating a limp mode or other mechanical (fuel or ignition system component) failures.
There are a few reasons why your car might be struggling to accelerate. It could be due to a problem with the timing belt, the spark plugs, or the fuel injectors. It could also be because you have a dirty air filter or a clogged fuel filter. The fuel system may also be low on fuel.
The yellow oil warning light comes on when either the oil temperature gets too high, or the oil level or pressure is too low. If the oil is not lubricating the engine effectively, it could lead to expensive or even irreparable engine damage, so it`s important to act quickly.
A flashing orange light means that there is a problem that could affect how the car drives or handles, such as an engine misfire. You might be able to feel your car shake, or the engine could suddenly sound different. If this light comes on, you should take your car to be inspected immediately.
The average cost for a BMW 328i Check Engine Light Diagnosis & Testing is between $143 and $180. Labor costs are estimated between $143 and $180.
The reasons for a check engine light turning on can range from something minor like a loose gas cap to something more serious like a faulty catalytic converter. It could even be a sign of internal engine failure. Ignoring the problem can turn a potentially quick fix into a costly and time-consuming repair.
The emissions/exhaust system is the most likely culprit for many check engine lights being illuminated. There could be an exhaust leak or a problem with the catalytic converter. The mass airflow sensor (MAF) is another sensor that is easily tripped or can fail.
Low Oil and Check Engine Light
However, low oil pressure, which can be caused by low oil levels, can be a reason for the check engine light to turn on. Low oil pressure can seriously interfere with your car`s performance and disable your vehicle if not addressed immediately.
Check your gas cap first. Many vehicles have a loose gas cap indicator that will be triggered before your check engine light comes on. If your gas cap is loose or the seal is not tight, the vapor leakage can cause your fuel system to trigger the check engine light.
Press the odometer`s Trip and Reset buttons while turning the ignition key ON. After turning the key ON, release the odometer Reset and Trip buttons to check if the Diagnostic Trouble Code or DTC appears on the odometer display.
“Limp Mode” – If your car won`t accelerate over 25 or 40 mph, it could have engaged `limp mode. ` It is also known as a limp home mode, and it acts as a preservation feature. It is meant to get you home, to an auto mechanic, or safely off the road without destroying your engine.
Most of the time this is triggered due to a problem within the transmission. Either minor like low or leaking transmission fluid, a loose or malfunctioning sensor or a major component problem.
If you are driving at 120 mph, it is possible that your vehicle is hitting the speed governer. This speed governer will prevent the vehicle from going past a certain speed by limiting engine power and reducing rpms.
The leading cause of this type of problem is an exhaust restriction, like a clogged catalytic converter. It could also be an intake restriction, like a defective MAF/MAS sensor.
Yes. While the damage may seem small initially, the longer you drive with a bad oxygen sensor, the worse the damage will become. Eventually, you may experience rough idling, poor acceleration, engine misfires, an illuminated check engine light, and failed emission tests.
Symptoms of low oil include your engine feeling sluggish. It may suffer from poor acceleration and you could find yourself sitting behind the wheel wondering what those knocking and ticking noises might be?
