Buyer's Guide to Audi Q5 Ignition Parts

How Ignition Works

Ignition occurs when the ignition coil transforms the relatively low ignition voltage into the high voltage that fires the spark plugs. The plugs use that to kindle the mixture of air and fuel that's inside the engine. That produces the combustion that moves your SUV down the road.

How Do I Spot Ignition Problems?

Even a high-quality ignition such as the one in your premium SUV can wind up going bad. Signs of failure include:

  • Flickering dash lights
  • Your engine keeps stalling
  • You can't start your SUV
  • You're unable to turn the ignition key or get no response when pressing the "Start" button
