This explosion is what moves the pistons and makes the engine run. The spark plug wires transport the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are harmful 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, fundamental to more fancy repairs.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or substitute item can wreak havoc on your 2014 BMW 640i if it’s not installed properly. These aftermarket parts and accessories can ditch the battery, trigger the check engine light, or even prevent the vehicle from starting.

Getting accessories, exceptionally aftermarket parts and accessories, or using OEM parts first place might cost a few bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your catalytic converter is harmful or going harmful. The catalytic converter is a part of your 2014 BMW 640i’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 all BMW service. If you have an issue with your catalytic converter and don't get it revamped, your 2014 BMW 640i 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 substitute problems from overheating.
  • One of the most natural and many cause is that your 2014 BMW 640i gas cap is loose, damaged or missing. The gas cap for your 2014 BMW 640i 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 harmful 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 fancy. If your check engine light turns on shortly after you put gas in your 2014 BMW 640i, first thing you should check is to make convinced 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 2014 BMW 640i is all direct. 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 some 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 usual service coupons and specials.
  • Your 2014 BMW 640i has a vacuum leak. All BMW 640i has a vacuum system that performs a wide variety of functions. The vacuum system also helps reduce destructive 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 bare out and crack, exceptionally if they’re exposed to extraordinary heat or extreme bitter.
  • Your O2 Sensor (Oxygen Sensor) needs to be replenished. The Oxygen sensor, admitted 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 keen 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 2014 BMW 640i's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose the proper variety of air and fuel that enters the cylinders in your engine. A harmful O2 sensor can also cause a car to fail an emissions test.
  • Your mass airflow sensor (known as MAF) needs to be replenished. The mass airflow sensor in your BMW 640i is what determines how much fuel is basic 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 big changes, like altitude. If your BMW 640i 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 harmful mass airflow sensor.
