When your check engine light comes on, this could be as proper as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a distinguishable problem that could cause distinguishable damage to your engine and come with a exceptional repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow commonly means something less distinguishable but a flashing check engine light implies that your vehicle’s engine is in distinguishable trouble and service is fundamental urgently. If your check engine light is flashing in your 2020 BMW 330i, we tremendously advocate not to commute the vehicle and schedule BMW service today. Below is a list of the most well-known reasons your check engine light can come on:

  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2020 BMW 330i’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is usually caused by neglected maintenance, which is why Plaza BMW offers a complimentary multi-point inspection with every BMW service. If you have an issue with your catalytic converter and don't get it repaired, your 2020 BMW 330i will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause other problems from overheating.
  • Your mass airflow sensor (known as MAF) needs to be interchanged. The mass airflow sensor in your BMW 330i is what determines how much fuel is necessary to run your engine efficiently by measuring the jettison of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to definite changes, like altitude. If your BMW 330i is having trouble starting, idling rough or has a rapid change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Your 2020 BMW 330i has a vacuum leak. Every BMW 330i has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack, highly if they’re exposed to exceptional heat or extreme frigid.
  • New Spark Plugs or Plug Wires are necessary for your 2020 BMW 330i. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or departed, you will experience poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, leading to more expensive repairs.
  • One of the most known and frequent cause is that your 2020 BMW 330i gas cap is loose, damaged or missing. The gas cap for your 2020 BMW 330i serves multiple purposes. It prevents gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a bad fuel cap? If your gas cap is departed or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on shortly after you put gas in your 2020 BMW 330i, initial thing you should check is to make courageous the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2020 BMW 330i if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound common, bring your 330i to BMW and have our team of certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, highly aftermarket parts and accessories, or using OEM parts initial place might price a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your O2 Sensor (Oxygen Sensor) needs to be interchanged. The Oxygen sensor, known as the O2 sensor, measures the jettison of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less adequate when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2020 BMW 330i's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to represent the proper mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
  • The battery is low or dead. The battery in your 2020 BMW 330i is every astonishing. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone. Today’s car batteries last much longer than they did a bit decades ago, and they don't really require maintenance. The price of a new one depends on the type of BMW you drive, but check our present service coupons and specials.
