Over time, vacuum hoses can dry out and crack, especially if they’re exposed to intense heat or extreme cold.
  • The battery is low or dead. The battery in your 2017 Audi S8 is each critical. Without a vehicle battery, your vehicle won’t start, light up the road in front, play the radio or charge your phone.

  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2017 Audi S8 if it’s not installed perfectly. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting.

  • One of the most common and frequent cause is that your 2017 Audi S8 gas cap is loose, broken or missing. The gas cap for your 2017 Audi S8 serves numerous 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 faulty 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 expensive. If your check engine light turns on rapidly after you put gas in your 2017 Audi S8, 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.

As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your Audi S8 is having trouble starting, idling rough or has a sudden quick change in the position of the throttle pedal, this could be a essential sign of a faulty mass airflow sensor.

If there is excess oxygen in your exhaust system, fuel burns more quickly and your car 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 significant damage to your catalytic converter and your 2017 Audi S8'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.

If you have an issue with your catalytic converter and don't get it repaired, your 2017 Audi S8 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other perilous problems from overheating.
