What Causes Your BMW’s Check Engine Light to Come On?

What Causes Your BMW’s Check Engine Light to Come On?

BMW cars are incredibly intelligent and meticulously crafted machines. As a result, your BMW is equipped with various technologically-advanced systems to safeguard you and your vehicle against the adverse effects of severe components failure. The check engine light is one such system. Let’s discuss more about how the check engine light works and the types of component failures that can result in this warning light illuminating on your dashboard.

The Purpose of the Check Engine Light

The Check Engine Light (CEL), also known as Engine Management Light (EML), is a warning indicator found on the dashboard of your BMW. This light illuminates when more serious issues are detected within any of your vehicle’s systems or components that are connected to the engine and its exhaust system.

The CEL is connected directly to the Engine Control Unit (ECU) of your BMW, which is the vehicle’s main computer. As soon as the ECU detects an issue with one of the above systems, it sends out an error code and triggers the check engine light. The error code can then diagnose and repair the issue properly.

The severity of the problem determines a driver’s response to the CEL. Even if your vehicle appears to be operating correctly, you should reduce your speed and come to our certified repair center. You should pull over if the light illuminates red or if your vehicle does not appear to be safe. In that case, contact a tow service to bring your car to our repair facility.

Reasons Why the Check Engine Light (CEL) May Come On

Many factors can cause this essential warning light to illuminate. Here are a few of the most common reasons this may occur, how hazardous their impact might be to your car, and how you should handle it:

  • Damaged Fuel Pumps: The fuel pump delivers pressurized fuel to the fuel injectors in the engine. If the fuel pump is damaged, it will not function appropriately, preventing the power from entering the machine correctly, resulting in rough running. As a result, the check engine light will be activated by the ECU, and your BMW engine is at a high risk of experiencing misfiring.
  • Loose Fuel Caps: Drivers are most commonly guilty of this problem when distracted at the pump and do not correctly tighten their fuel cap. When the cap is loose, extra air can enter the tank and displace the pressure in the tank. Consequently, one of the many sensors in the car will detect a problem and alert the engine control unit. In general, this is the most common and easiest cause of the illumination of the check engine light and should be eliminated first.
  • Worn Vacuum Hoses: The vacuum hoses are necessary to channel fresh air and exhaust around the engine to ensure optimum performance. The vacuum hose is made of rubber material, making them susceptible to breaking down due to the high temperatures inside a machine. This can eventually lead to cracks or deterioration. As a result, the engine’s sensors may report problems to the ECU because the precise balance of gases has been tipped, causing the check engine light to appear on the dashboard.
  • Clogged Particulate Filters: The particulate filter is most commonly found on diesel-powered vehicles, although it is now introduced to gasoline-powered cars. As a result of combustion processes, particles such as soot are produced. The particulate filter is responsible for collecting these particles. Once the filter becomes clogged, soot will begin to settle within the engine and start to contaminate the delicate components. There is a pressing need to resolve this issue as soon as possible, as if the filter becomes damaged beyond repair, you are likely to face extensive costs.

The Benefits of Regular BMW Brake Maintenance Service in Hellertown

The Benefits of Regular BMW Brake Maintenance Service in Hellertown

The BMW is a luxury car built with high performance, and every BMW driver wants to enjoy every comfort it has to offer and trust in the safety features built into their model. When we think of safety in a car, the first thing that comes to mind is the brakes. If your brakes are not in good order, then you are putting yourself and other road users at risk of an accident.

It is important to note, however, that driving behavior affects the life of a brake considerably. Drivers who often come to a sudden halt will need to change their brake pads more frequently than those who cruise to a stop.

The brakes of cars moving slowly through cities are more easily worn than those of cars traveling on wide rural roads, and the brakes of cars traveling downhill are worn down faster than those traveling on flat suburban roads. For your car’s brakes to perform properly when you need them, regular maintenance is required.

The Benefits of Regular Brake Maintenance

Here are some benefits you can expect as a driver when you have your vehicle’s brakes serviced on a regular basis.

  • Quiet Ride: Having your brakes serviced can reduce the amount of stress and hassles you encounter on a daily basis by providing a calmer, more peaceful environment in your car. The smoother ride that your properly maintained brakes provide will lessen noise from outside your cabin, allowing you to enjoy conversation or music instead of background noise on your journey. If you wish to enjoy this tranquility, have your BMW brakes serviced.
  • Improved Fuel Efficiency: You might also save money on gas if you have well-maintained brakes. If your brakes work properly, less energy is wasted, which means less gasoline is required to keep your car on the road.
  • More Accurate Driving: You will enjoy driving more when your brakes function properly, as they will enhance your vehicle’s ability to manage tight corners and other maneuvers. Having more control over your car will make your journey to your next destination more enjoyable.
  • Better Driving Experience: One of the most important parts of vehicle safety is the ability to stop immediately after you apply the brake. If you maintain your brake pads and other components of your braking system, it will improve their reactivity, allowing you to respond to changing road conditions more efficiently. It will prevent you from having a potential mishap and keep you and others safe.
  • Save money: It is in everyone’s interest to have cheaper car maintenance. Getting preventative brake service will save you money in the long run compared to waiting for emergencies. A good brake system can prevent damage to other parts of your car, which can save you money in the long run.
  • Extend the Life of Your Brakes: If you don’t maintain your vehicle’s brakes properly, you’ll have to replace them very often. You can reduce the amount of money you spend on parts replacement by maintaining your brakes with routine maintenance visits.
  • Maintain the Legality of Your Vehicle: A car must satisfy specific requirements in order to be legally certified to drive on the road. You need to carry out regular inspections to ensure that all of its systems are functioning well. Checking the condition of your brakes is part of that inspection. Maintaining your vehicle’s brakes will ensure that it passes its inspection.

HVAC is an acronym for Heating, Ventilation, and Air Conditioning, and it is responsible for regulating the temperature in the cabin of your BMW. Apart from providing air conditioning or heating, it also helps defrost the windshield for clearer vision.

If the system is not adequately maintained and serviced, it can develop problems. Depending on the time of the year it fails, your driving experience can become unpleasant and frustrating. Knowing the symptoms to look for will help save you from the brutal summer heat or freezing winter cold. Let’s dive deeper into how to recognize a failing HVAC system, its causes, and how to solve the problem.

Symptoms of HVAC Failure in your BMW

One or more of the following signs may indicate that your vehicle’s HVAC system is failing.

  • Little or No Airflow: One of the first indicators is that the airflow becomes significantly lower than expected. You may notice that you need to increase the speed of your blower to achieve the same comfort level previously. This is one of the first indicators of the problem, and you may also discover that your defrosters are not operating properly.
  • Unusual noises when the fan is on: When the fan is turned on, you may hear strange noise coming from inside the vent. You may notice popping or slapping This is usually the result of an object being sucked in the vent. You may also hear a spinning noise that gets louder as the heating and cooling settings are increased. You may be able to dislodge a foreign object that you see, but if the vent is blocked further down the system, it will require a professional to inspect it.
  • Runs at a single speed: If the problem persists for a long time, you may lose the ability to change the settings. It may be difficult to switch it up to the highest setting. Sometimes, the blower will not work at all, even when you turn up the setting to try to get more cool/warm air to blow out.
  • Inefficient air temperature exiting vents: It’s common for your air conditioner to take a few moments to cool down when you turn it on, although this usually requires less time in a BMW car due to its strong efficiency. If you observe that the air never cools enough, it’s possible that you have a Freon leak. This can be replaced at a shop for you.

Common Causes of HVAC Blower Failure

Your BMW’s HVAC blower can fail for a variety of reasons.

  • Blower Motor Relay Failure: The heating, ventilation, and air conditioning system, as well as the blower, are made up of many components that all work together collectively to keep you comfortable. When one of these components fails, the blower and system can degrade or stop working entirely. To enable the system to function, the blower system relies on many electrical components and connections. When one of these relays breaks down, the blower motor loses its ability to push cool or warm air through the vents. This usually needs replacement of the motor.
  • Wear and tear: The blower in your HVAC system is subject to typical wear and tear. A vehicle’s natural breakdown of parts occurs over its lifetime. Although it is irritating to have to replace parts on your BMW, it is unavoidable. Components deteriorate and break as a result of regular usage, the passage of time, and exposure to the elements.
  • Manufacturer’s defect: Occasionally, a problem arises during the production process. Even though BMW has high standards for all of its automobiles, errors do occur. Unknown to BMW, a defective component may have slipped through the inspection process.

Call Our Experts to Fix a Water Pump Failure in a BMW in Hellertown

The water pump is the heart of a BMW’s cooling system. It circulates the coolant through the engine block, cylinder heads, and radiator. If it fails, your BMW will overheat and cause major (and expensive) damage to the engine. Let’s discuss the functions of the water pump in your BMW, why it may fail and what to do when it fails.

What is the function of the water pump in a BMW?

The water pump is responsible for circulating coolant to keep your engine cool. (Coolant is usually made of antifreeze and water combined.) The pulley on the front of the water pump spins the impeller inside. The impeller is designed to push coolant liquid through the cooling system. As it passes through the system, it absorbs heat from the engine and then returns to the radiator to dissipate that heat.

Like many parts of a BMW, there are two types of water pumps: mechanical and electric. Mechanical pumps have been used for years, but electric pumps are quickly replacing them.

  • Mechanical Water Pump: A mechanical water pump has a simple design with an impeller driven by a belt and pulley, usually attached to either the crankshaft or camshaft. As long as the engine is running there will be coolant being pumped throughout the cooling system.
  • Electric Water Pump: An electric water pump runs only when needed by using an electric motor instead of a belt. When you start your car and begin driving, an electric signal tells the motor to turn on, which begins pumping coolant throughout the cooling system.

The Most Common Causes of a Water Pump Failure

  • Wear and Tear: The most common reason for a water pump failure is due to age/wear. The bearings in the water pump eventually wear out, which causes the shaft and impellers to become loose. The loose pieces then rattle around the inside of the pump and cause damage to the internal components. If you are hearing a rattling or knocking noise coming from your engine bay, it’s a good idea to check your water pump for any signs of damage.
  • Poor cooling system maintenance: The cooling system is responsible for circulating coolant through your engine to keep it at the right temperature. It also lubricates the bearings of the timing belt (or chain). It is important to check that this system is working properly without faults, so timely maintenance is necessary.
  • Coolant leaks: Coolant is what keeps everything cool in your car’s engine. If you have a leak, this means that there won’t be enough coolant circulating through the system to properly and your engine can overheat. This can cause major damage.
  • Worn Seals: Like most pumps, the water pump in your BMW has seals that prevent coolant from leaking out when it is being pumped through the engine block and cylinder heads. As those seals begin to wear out, you may begin to see puddles of coolant underneath your car after it has been parked for any length of time. Eventually, those worn seals will cause your water pump to fail altogether if they are not repaired or replaced on time.
  • Coolant contamination: There could be debris floating around in your coolant reservoir and hoses. Dirt can build up on the impeller blades over time and cause clogs, leaks, and thick coolant.

Signs Your BMW Water Pump has Failed

If you notice your engine temperature gauge rising or steam coming out of your hood, pull over immediately and shut off your car. You should then call for a tow as soon as possible. You do not want to drive with an overheating engine, since it can lead to serious damage and expensive repairs.
