Some simple regular maintenance will save you a lot of money in the long run. If the gap in your spark plug widens due to normal erosion, it leads to an increased voltage being required to create a spark in the chamber. The increased voltage demands more current flow through the primary circuit and this increased current flow can overload the primary transistor.
Keeping all these components in good running condition is also a big help towards keeping your coils in a good working condition.Some ignition systems will use one coil to provide the spark for all of the cylinders, however most newer designs use an individual coil for each cylinder.

Usually a faulty ignition coil will produce a few symptoms that alert the driver of a potential issue.Vr hand tracking
One of the most common symptoms associated with a faulty ignition coil is engine performance issues. As the ignition coils are among the ignition system's most vital components, an issue can cause spark to be compromised, which can quickly lead to performance issues.

Powered by WordPress.Audi cars are built to last for a long time. Unfortunately, just like all other man-made machines, they require ongoing care and maintenance in order to continue running well.
Forgone maintenance can come to a head when you begin to notice serious symptoms of malfunction in your Audi. One of the more serious signs that your Audi is in need of servicing is engine misfiring. Engine misfiring is a common symptom that can be due to several issues or origin. If you experience engine misfiring in your Audiit is critical to have the problem checked out by an Audi specialist who can perform a thorough, accurate differential diagnosis to isolate the source of the problem.
Here is a bit more information about engine misfiring in your Audi, including the common reasons for engine misfiring and concerning symptoms you should be aware of. Engine misfiring can be a symptom of a problem with one of the various parts of the ignition system. Usually, when engine misfiring occurs and the problem is traced back to the ignition system, typically spark plugs are the culprit.
Spark plugs can wear out over time, or can begin to malfunction due to another error in the system, where they are unable to generate enough power or heat to spark ignition. Another potential source of error is in the ignition system wiring. Again, wiring can become worn overtime, which is especially true in cars that commonly experience significant weather chances.
Another common reason for engine misfiring is clogged fuel injectors. Fuel injection systems have evolved over time, but they still encounter issues such as clogging. You can take your Audi to have the fuel injectors inspected for clogging, and they can even be cleaned or replaced if need be. When fuel injectors become clogged, the necessary amount of fuel cannot reach the engine to start the combustion process.
If the right fuel to air ratio is not achieved, the engine will misfire—often at the most inconvenient times.
Top 7 Common Audi Repair Issues and Costs To Fix Them
Your Audi automotive technician will want to inspect the fuel injection system to determine if the injectors are working properly.
