As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your VW 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 damaging mass airflow sensor.

If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less direct 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 2012 VW GTI's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to advocate 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.

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 erstwhile 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 rapidly after you put gas in your 2012 VW 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.
• New Spark Plugs or Plug Wires are basic for your 2012 VW 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.

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, dominant to more costly repairs.
• The battery is low or dead. The battery in your 2012 VW GTI is every forceful. 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 numerous decades ago, and they don't absolutely require maintenance.

• Your 2012 VW GTI has a vacuum leak. Every VW GTI has a vacuum system that performs a wide collection of functions. The vacuum system also helps decrease destructive 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 barren out and crack, excessively if they’re exposed to forceful heat or extreme freezing.
• Your catalytic converter is damaging or going damaging. The catalytic converter is a part of your 2012 VW 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 usually caused by neglected maintenance, which is why Nalley Volkswagen of Alpharetta offers a complimentary multi-point inspection with every VW service.
