What could cause the check engine light to come on in a 2020 BMW 325i?

When your check engine light comes on, this could be as commonplace as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a dangerous problem that could cause dangerous damage to your engine and come with a grand repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow naturally means something less dangerous but a flashing check engine light implies that your vehicle’s engine is in dangerous trouble and service is necessary immediately. If your check engine light is flashing in your 2020 BMW 325i, we excessively endorse not to drive the vehicle and schedule BMW service today. Below is a list of the most common reasons your check engine light can come on:

  • New Spark Plugs or Plug Wires are decisive for your 2020 BMW 325i. 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 destructive or old, 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.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, active as the O2 sensor, measures the payment of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less efficient 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 325i's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to illustrate the right mixture of air and fuel that enters the cylinders in your engine. A destructive O2 sensor can also cause a car to fail an emissions test.
  • One of the most active and frequent cause is that your 2020 BMW 325i gas cap is loose, damaged or missing. The gas cap for your 2020 BMW 325i 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 destructive fuel cap? If your gas cap is old 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 rapidly after you put gas in your 2020 BMW 325i, first thing you should check is to make confident the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your 2020 BMW 325i has a vacuum leak. Each BMW 325i has a vacuum system that performs a wide mixture 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, chiefly if they’re exposed to intense heat or extreme bitter.
  • Your catalytic converter is destructive or going destructive. The catalytic converter is a part of your 2020 BMW 325i’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 ordinarily caused by neglected maintenance, which is why Richmond BMW offers a complimentary multi-point inspection with each BMW service. If you have an issue with your catalytic converter and don't get it repaired, your 2020 BMW 325i 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 added problems from overheating.
  • The battery is low or dead. The battery in your 2020 BMW 325i is each amusing. 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 few 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 actual service coupons and specials.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or added item can wreak havoc on your 2020 BMW 325i if it’s not installed appropriately. These aftermarket parts and accessories can deposit the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound contemporary, bring your 325i to BMW and have our team of certified mechanics ensure that your aftermarket items were installed appropriately and aren't causing any issue. Getting accessories, chiefly aftermarket parts and accessories, or using OEM parts first place might cost a tiny bit more but could save you money from having to get poor function and damage caused by poor installation function corrected.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your BMW 325i is what determines how much fuel is decisive to run your engine efficiently by measuring the payment of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to actual changes, like altitude. If your BMW 325i is having trouble starting, idling rough or has a sudden change in the position of the throttle pedal, this could be a sign of a destructive mass airflow sensor.
