Well, the dreaded check engine light is every driver’s concern and your BMW is no exception. BMW owners fear the check engine light because of the wide range of issues it can potentially indicate with your vehicle. However, there are some specific issues that cause the check engine light to flash in BMW & here in this article, we will glance through these problems that require immediate attention on your part.

Why Does The Check Engine Light Flash?

Malfunctioning Oxygen Sensor

BMW is notorious for the problems affecting its sensors and the malfunctioning oxygen sensor features at the top of the list that cause the check engine light to flash on the dashboard. The power-packed performance of your high-end car is to a large extent dependent on tiny sensors like the oxygen sensor.

The oxygen sensor popularly called the O2 sensor is responsible for monitoring the amount of unburnt oxygen present in the exhaust gases & the data collected is routed back to the onboard computers which adjusts the air/fuel mixture entering the cylinders which alters the performance of your car.

Now, a faulty O2 sensor is going to send erroneous information to the onboard computers and this will create havoc with the functioning of the engine leading to the illumination of the check engine light. It is advisable to get your O2 sensor replaced because it has the potential to damage the other critical parts of your BMW.

Damaged Catalytic Converter

The catalytic converter ensures your BMW meets the stringent pollution control guidelines in place and being such an important part any issues with its functioning will activate the warning light.

The catalytic converter works in tune with the exhaust system of your BMW & converts the carbon monoxide generated during the combustion process into less harmful carbon dioxide. Perhaps you would like to do everything on your part to avoid getting caught with a failed catalytic converter in your luxury car.

This is because the catalytic converter is arguably one of the most expensive parts in your vehicle & replacing it with a new one would definitely inflate your repair bills. The best way to take care of your catalytic converter is to get it cleaned by a BMW specialist during your regular oil change schedule.

EGR Valve Failure

The Exhaust Gas Recirculation (EGR) valve is often the least talked about but one of the most vital components whose failure can trigger the check engine light. The EGR valve helps in the efficient functioning of the engine by lowering the amount of nitrogen oxide coming out of the engine of BMW.

The EGR valve recirculates the exhaust gases back into the combustion chamber where they are burnt completely thus reducing emissions from your high-end car. Most of the time a clogged EGR valve leads to the flashing of the warning light on the dashboard.

Inadequate Fluid Levels

Probably know that there are a host of fluids in your BMW that help in its smooth running & better performance. From the engine oil to the transmission fluid and coolant all these fluids do have a bearing on the functioning of the engine.

Often it is observed that the presence of inadequate levels of any of these fluids in BMW can trigger the check engine light. All these fluids do have a bearing on the functioning of the engine & lower levels of fluids due to any reason from leaks to irregular maintenance schedules is definitely a cause of concern for your car.

Repercussions Of Ignoring The Warning Light

Sometimes drivers do have the habit of ignoring the check engine light and keep on driving. Well, this is not at all advisable because going through the above-discussed factors one thing is crystal clear ignoring these issues is going to have severe ramifications for your engine.

Nobody likes to drive a BMW whose engine is behaving erratically and that is why initiating remedial measures is necessary.
