What could cause the check engine light to come on in a VW Jetta GLI?

When your check engine light comes on, this could be as cogent as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a alarming problem that could cause alarming wear and tear to your engine and come with a colossal repair bill. Depending on your make and model, the check engine light will illuminate or blink. A active glow typically means something less alarming but a blinking check engine light illustrates that your vehicle’s engine is in alarming trouble and service is needed today. If your check engine light is blinking in your VW Jetta GLI, we incredibly recommend not to drive the vehicle and schedule VW service straightaway. Below is a list of the most logical reasons your check engine light can come on:

• One of the most classic and innumerable cause is that your Volkswagen Jetta GLI gas cap is loose, damaged or missing. The gas cap for your VW Jetta GLI 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 damaging fuel cap? If your gas cap is traditional 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 costly. If your check engine light turns on immediately after you put gas in your VW Jetta GLI, first thing you should check is to make courageous the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
• Your catalytic converter is damaging or going damaging. The catalytic converter is a part of your VW Jetta GLI’s exhaust system. The catalytic converter's work is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is commonly 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 VW Jetta GLI 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 other problems from overheating.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your VW Jetta GLI is what determines how much fuel is fundamental to run your engine efficiently by measuring the dump 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 VW Jetta GLI is having trouble starting, idling rough or has a fast change in the position of the throttle pedal, this could be a sign of a damaging mass airflow sensor.
• Your Volkswagen Jetta GLI has a vacuum leak. Every VW Jetta GLI has a vacuum system that performs a grand 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 arid out and crack, notably if they’re exposed to intense heat or extreme chilly.
• New Spark Plugs or Plug Wires are fundamental for your VW Jetta GLI. 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 damaging or traditional, 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 wear and tear to ignition coils and O2 sensors, essential to more costly repairs.
• The battery is low or dead. The battery in your VW Jetta GLI is every exciting. 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 innumerable decades ago, and they don't really require maintenance. The price of a new one depends on the type of VW you drive, but check our current service coupons and specials.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, admitted as the O2 sensor, measures the dump of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less fair 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 wear and tear to your catalytic converter and your VW Jetta GLI'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 damaging O2 sensor can also cause a car to fail an emissions test.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your Volkswagen Jetta GLI if it’s not installed accurately. These aftermarket parts and accessories can ditch the battery, trigger the check engine light, or even avert the vehicle from starting. If these issues sound attentive, deliver your Jetta GLI to VW and have our unit of certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, notably aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could save you money from having to get poor work and wear and tear caused by poor installation work corrected.
