Check Engine Light Service 2021 VW Atlas

What do you do when you’re driving along in your VW Atlas and suddenly, a yellow light illuminates on your dash and says "Check Engine".

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that can rapidly identify the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our VW auto repair mechanics at Larry H. Miller Volkswagen Lakewood. There are still a number of essentially inexpensive code readers that are designed for do-it-yourselfers, should you pick that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the explicitly correct issue and repair it.

What could cause the check engine light to come on in a 2021 VW Atlas?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Likewise, the check engine light could still be a warning of a significant problem that could cause serious damage to your engine and come with a hefty and pricey repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow generally means something less serious but a flashing check engine light reveals that your vehicle’s engine is in significant trouble and useful service is needed quickly. If your check engine light is flashing in your 2021 VW Atlas, we tremendously suggest not to drive the vehicle and schedule VW service today. Below is a list of the most common reasons your check engine light can come on:

• Your 2021 VW Atlas has a vacuum leak. Every VW Atlas has a vacuum system that performs a wide variety of functions. The vacuum system still helps lower adverse 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, exceptionally if they’re exposed to intense heat or extreme cold.
• The battery is low or dead. The battery in your 2021 VW Atlas is every essential. 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. 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, 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 broken sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your 2021 VW Atlas's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the precisely correct combination of air and fuel that enters the cylinders in your engine. A broken O2 sensor can still cause a car to fail an emissions test.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2021 VW Atlas if it’s not installed properly. These aftermarket parts 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 Atlas to VW and have our team of talented certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, exceptionally aftermarket parts and accessories, or utilizing OEM parts 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.
• New Spark Plugs or Plug Wires are needed for your 2021 VW Atlas. The spark plugs are the part of your engine that ignites the air/fuel combination 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 decreased 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 pricey repairs.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2021 VW Atlas’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 Larry H. Miller Volkswagen Lakewood offers a free multi-point check with every VW service. If you have an issue with your catalytic converter and don't get it repaired, your 2021 VW Atlas 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 dangerous problems from overheating.
• One of the most common and frequent cause is that your 2021 VW Atlas gas cap is loose, damaged or missing. The gas cap for your 2021 VW Atlas serves various purposes. It prevents dangerous 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 broken 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 expensive. Luckily, to replace a gas cap isn't pricey. If your check engine light turns on quickly after you put gas in your 2021 VW Atlas, 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 mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your VW Atlas 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 certain changes, like altitude. If your VW Atlas is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a important sign of a broken mass airflow sensor.
