Buyer's Guide to Audi Ignition Parts

How Audi Ignition Works

After you press that button or turn the key, your battery, ignition coil, and starter solenoid combine to send an electric charge to the spark plugs. The plugs then capture that charge and use it to ignite the air and fuel mixture inside the engine. That creates the combustion you need to head off down the road.

How to Spot Ignition Problems

Even the best ignition parts, like the ones in your car or SUV, don't last forever. Signs of trouble include:

  • Flickering dashboard lights
  • Issues starting your vehicle
  • The starter motor won't engage
  • You're unable to turn the ignition key or depress the button

Why Buy Genuine Audi Ignition Parts Over Generic?

Your manufacturer makes the only ignition parts that are guaranteed to be compatible with your model, ensuring the performance you want. Not only do generic parts not come with that same promise, but they may not fit right into place -- requiring more effort from you than is warranted.
