If your check engine light is flashing in your BMW Z4, we remarkably recommend 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:

  • Your BMW Z4 has a vacuum leak. Every BMW Z4 has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower unhealthy 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 cold.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your BMW Z4 if it’s not installed properly. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound familiar, bring your Z4 to BMW and have our team of talented certified mechanics guarantee that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM components first place might cost a little bit more but could help you save considerably from having to get poor work and damage caused by poor installation work corrected.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your BMW Z4 is what determines how much fuel is required 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 Z4 is having trouble starting, idling rough or has a sudden quick change in the position of the throttle pedal, this could be a critical sign of a damaged mass airflow sensor.
  • One of the most common and frequent cause is that your BMW Z4 gas cap is loose, damaged or missing. The gas cap for your BMW Z4 serves various purposes. It prevents unpredictable 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 damaged 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 and be more pricey. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on swiftly after you put gas in your BMW Z4, first thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • The battery is low or dead. The battery in your BMW Z4 is every important. Without a vehicle battery, your vehicle won’t start, light up the road in front, play the radio or charge your phone. Today’s vehicle batteries last much longer than they did a few decades ago, and they don't genuinely require maintenance. The price of a new one depends on the type of BMW you drive, but check our current service coupons and specials.
  • 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 more quickly 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 damaged sensor can not only affect your miles per gallon, but it can cause serious damage to your catalytic converter and your BMW Z4's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the exactly correct mixture of air and fuel that enters the cylinders in your engine. A damaged O2 sensor can also cause a vehicle to fail an emissions test.
  • New Spark Plugs or Plug Wires are required for your BMW Z4. 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 smooth. 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 a evident 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 catalytic converter is bad or going bad. The catalytic converter is a part of your BMW Z4’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 constantly neglected maintenance, which is why Nalley BMW of Decatur offers a complimentary multi-point check with every BMW service. If you have an issue with your catalytic converter and don't get it repaired, your BMW Z4 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other perilous problems from overheating.
