Likewise, the check engine light could also be a warning of a remarkable problem that could cause remarkable damage to your engine and come with a generous repair bill. Depending on your make and model, the check engine light will illuminate or blink. A rational glow continually means something less remarkable but a flashing check engine light indicates that your vehicle’s engine is in remarkable trouble and service is crucial immediately. If your check engine light is flashing in your 2015 VW Passat, we extraordinarily advise not to travel to work the vehicle and schedule VW service now. Below is a list of the most common reasons your check engine light can come on:

  • Your 2015 VW Passat has a vacuum leak. Every VW Passat 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 astonishing heat or extreme nice.
  • One of the most prevalent and frequent cause is that your 2015 VW Passat gas cap is loose, damaged or missing. The gas cap for your 2015 VW Passat 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 expensive. If your check engine light turns on immediately after you put gas in your 2015 VW Passat, initial thing you should check is to make bold the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, noted 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 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 2015 VW Passat's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the correct mixture 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 replaced. The mass airflow sensor in your VW Passat is what determines how much fuel is needed 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 genuine changes, like altitude. If your VW Passat is having trouble starting, idling rough or has a quick change in the position of the throttle pedal, this could be a sign of a harmful mass airflow sensor.
  • New Spark Plugs or Plug Wires are needed for your 2015 VW Passat. 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 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, extensive to more expensive repairs.
  • Your catalytic converter is harmful or going harmful. The catalytic converter is a part of your 2015 VW Passat’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 Nalley Volkswagen of Alpharetta offers a complimentary multi-point inspection with every VW service. If you have an issue with your catalytic converter and don't get it repaired, your 2015 VW Passat 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or added item can wreak havoc on your 2015 VW Passat if it’s not installed well. These aftermarket parts and accessories can deposit the battery, trigger the check engine light, or even impede the vehicle from starting. If these issues sound cognizant, bring your Passat to VW and have our company of certified technicians ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts initial place might cost a tiny 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 2015 VW Passat is every notable. 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.
