This amber or yellow light is naturally labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an computerized probe tool that is used by our BMW auto repair mechanics at Plaza BMW. There are also a number of relatively correct code readers that are designed for do-it-yourselfers, should you choose that route too.

What could cause the check engine light to come on in a BMW 525i?

When your check engine light comes on, this could be as conspicuous as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a relentless problem that could cause relentless damage to your engine and come with a big repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow customarily means something less relentless but a flashing check engine light indicates that your vehicle’s engine is in relentless trouble and service is basic abruptly. If your check engine light is flashing in your BMW 525i, we extremely recommend not to drive the vehicle and schedule BMW service today. Below is a list of the most typical reasons your check engine light can come on:

  • One of the most common and frequent cause is that your BMW 525i gas cap is loose, damaged or missing. The gas cap for your BMW 525i 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 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 abruptly after you put gas in your BMW 525i, first thing you should check is to make hopeful the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your BMW 525i is what determines how much fuel is imperative to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your BMW 525i is having trouble starting, idling rough or has a speedy change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your BMW 525i’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 BMW 525i 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 back-up problems from overheating.
  • New Spark Plugs or Plug Wires are imperative for your BMW 525i. The spark plugs are the part of your engine that ignites the air/fuel alter 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 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, large to more expensive repairs.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be fewer 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 BMW 525i's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to find out the decent alter 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.
  • Issues with all aftermarket items. An aftermarket alarm, exhaust or back-up item can wreak havoc on your BMW 525i if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prohibit the vehicle from starting. If these issues sound common, bring your 525i to BMW and have our team of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing all issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might estimate a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • The battery is low or dead. The battery in your BMW 525i is every essential. 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 frequent 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 modern service coupons and specials.
  • Your BMW 525i has a vacuum leak. Every BMW 525i 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, especially if they’re exposed to intense heat or extreme nice.
