Will the check engine light reset itself?

The check engine light on your 2015 Audi A5 will usually shut itself off if the issue or code that caused it to turn on is fixed. 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 functional, 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 2015 Audi A5 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 Audi Creve Coeur so the light and code can be double-checked and reset.

2015 Audi A5 Check Engine Light Codes

The check engine light turning on can be quite intimidating to see that little light on your vehicle’s dashboard suddenly illuminates, but in reality, it is not something that should cause you to shut down in fear right away. If you hear the term, diagnostic trouble codes (DTC), these are just another name for check engine light codes. These are automotive computer codes stored by the ECM, also known as the OBD (on-board computer diagnostic system) in your A5. There are hundreds of different codes that your check engine light can represent. While that sounds daunting, with a little patience, tackling basic diagnostics will give you useful knowledge about your vehicle and will also allow that Check Engine Light to do what it is really supposed to do: be your guide. Unfortunately, obvious and helpful vehicle symptoms do not always accompany an illuminated Check Engine Light. Since there are hundreds of possible OBD codes, there are also hundreds of possible reasons for the light, including:

  • Loose Gas Cap or Missing Gas Cap
  • Emissions controls issues
  • Fuel and air metering systems problems
  • Computer output circuit issues
  • Bad Spark Plugs
  • Old Battery
  • Transmission issues
  • O2 Sensor
  • Ignition system faults
This is why it is important for someone who does not have a lot of automotive knowledge to not assume what a code means. When your check engine light comes on, you should get it checked out immediately by a certified Audi mechanic. If the engine light comes on due to a actual concern, you risk damaging your car further by not repairing the issue good away.

There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too.

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 also be a warning of a serious problem that could cause serious damage to your engine and come with a hefty repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something less serious but a flashing check engine light indicates that your vehicle’s engine is in serious trouble and service is needed immediately. If your check engine light is flashing in your 2015 Audi A5, we highly recommend not to drive the vehicle and schedule Audi service today. Below is a list of the most common reasons your check engine light can come on:

  • Your 2015 Audi A5 has a vacuum leak. Every Audi A5 has a vacuum system that performs a wide array 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, particularly if they’re exposed to important heat or extreme bleak.
  • 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 Audi A5's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to select the honest difference of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a automobile to fail an emissions test.
  • The battery is low or dead. The battery in your 2015 Audi A5 is every favorable. Without a automobile battery, your automobile won’t start, light up the road ahead, play the radio or charge your phone. Today’s automobile batteries last much longer than they did a few decades ago, and they don't truly require maintenance. The price of a new one depends on the type of Audi you travel to work, 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 reward of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less capable when it comes to fuel economy.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2015 Audi A5’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 constantly caused by neglected maintenance, which is why Audi Creve Coeur offers a complimentary multi-point inspection with every Audi service. If you own an issue with your catalytic converter and don't get it repaired, your 2015 Audi A5 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your automobile may run at a higher temperature, too, which can cause disparate problems from overheating.
  • Issues with all aftermarket items. An aftermarket alarm, exhaust or disparate item can wreak havoc on your 2015 Audi A5 if it’s not installed correctly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even avoid the vehicle from starting. If these issues sound natural, bring your A5 to Audi and own our team of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing all issue. Getting accessories, particularly 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.
  • One of the most modern and several cause is that your 2015 Audi A5 gas cap is loose, damaged or missing. The gas cap for your 2015 Audi A5 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 own a bad fuel cap? If your gas cap is former 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 pricey. If your check engine light turns on immediately after you put gas in your 2015 Audi A5, 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 Audi A5 is what determines how much fuel is fundamental to run your engine efficiently by measuring the reward of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to firm changes, like altitude. If your Audi A5 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 fundamental for your 2015 Audi A5. The spark plugs are the part of your engine that ignites the air/fuel difference 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 you're spark plugs or spark plug wires are bad or former, you will experience poor performance and reduced power. In some extreme cases, your engine will own 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 pricey repairs.
