The check engine light on your 2018 VW Golf GTI will usually shut itself off if the issue or code that caused it to turn on is serviced. For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will turn itself off. Likewise, if your catalytic converter is going equitable, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your 2018 VW Golf GTI light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Nalley Volkswagen of Alpharetta so the light and code can be double-checked and reset.

A steady glow continuously means something less hazardous but a twinkling check engine light indicates that your vehicle’s engine is in hazardous trouble and service is decisive promptly. If your check engine light is twinkling in your 2018 VW Golf GTI, we extremely recommend not to drive the vehicle and schedule VW service today. Below is a list of the most prevailing reasons your check engine light can come on:

• Your O2 Sensor (Oxygen Sensor) needs to be replenished. The Oxygen sensor, known as the O2 sensor, measures the deposit of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less practical 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 2018 VW Golf GTI's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to mean the right mixture 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.
• Your 2018 VW Golf GTI has a vacuum leak. Each VW Golf GTI has a vacuum system that performs a wide collection 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 energetic heat or extreme cold.
• The battery is low or dead. The battery in your 2018 VW Golf GTI is each basic. 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 actually require maintenance. The price of a new one depends on the type of VW you drive, but check our elaborate service coupons and specials.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or different item can wreak havoc on your 2018 VW Golf GTI if it’s not installed properly. These aftermarket parts and accessories can discharge the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound prevalent, bring your Golf GTI to VW and have our team of certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might value a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
• Your mass airflow sensor (known as MAF) needs to be replenished. The mass airflow sensor in your VW Golf GTI is what determines how much fuel is basic to run your engine efficiently by measuring the deposit 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 Golf GTI 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 bad mass airflow sensor.
• New Spark Plugs or Plug Wires are basic for your 2018 VW Golf GTI. 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 bad or long-established, 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, first-rate to more expensive repairs.
• One of the most sufficient and innumerable cause is that your 2018 VW Golf GTI gas cap is loose, damaged or missing. The gas cap for your 2018 VW Golf GTI 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 long-established 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 expeditiously after you put gas in your 2018 VW Golf GTI, 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.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 VW Golf GTI’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 frequently caused by neglected maintenance, which is why Nalley Volkswagen of Alpharetta offers a complimentary multi-point inspection with each VW service. If you have an issue with your catalytic converter and don't get it revamped, your 2018 VW Golf GTI 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 different problems from overheating.
