Your usually reliable VW hesitates a bit when you try to start it up and then spits, jerks, and misfires as you are driving along, even stalling at a stop light. This is not a moment to worry that your vehicle is possessed, but it is time to check your VW ignition coil. A critical element of your ignition system, the coil takes the small amount of voltage that the generator in your engine produces, excites it into thousands of volts, and transfers them to the spark plugs. These plugs then create the spark that ignites the fuel within your engine so your vehicle can start and operate. When symptoms of wear and failure appear, replacing your VW Audi ignition coil promptly is essential to ensuring that your vehicle starts when you need it to and keeps running smoothly and efficiently. Ignition coils are generally compatible with several models, such as the Audi, Jetta, or Golf, but it is important to check and make sure you choose one that fits your vehicle before attempting installation. Browse the large inventory on eBay to find the VW ignition coil that will keep the spark alive between you and your VW.
