Where is the Best Place to Repair Your Audi’s Spark Plug in Tempe?

by admin January 4, 2020

If an engine has no spark, it’s not going anywhere. This is because a spark is needed to ignite the fuel in your engine to kick off the combustion cycle and get your Audi moving. The part that is chiefly in charge of starting that reaction is the spark plugs. These hard-working parts are responsible for providing the spark that the engine vitally needs. They do this job continuously while your Audi is running, and therefore will need repair and replacement several times in your vehicle’s lifespan.

Let’s take a closer look at this important part. In this article, we’ll talk about how it does what it does, why it fails, and the best garage in Tempe to seek repairs.

The Spark Plugs

Spark plugs are small electrical components that in recent years have been tipped with precious metals such as iridium, yttrium, and platinum. They have 2 parts which are placed with a precise gap between them. This gap is where the spark jumps across when igniting the fuel. In working spark plugs, this spark is enough to ignite the pressurized air and fuel mixture inside the engine which begins combustion.

Spark plugs start to fail for 2 main reasons: either the electrical supply provided by the ignition coil becomes unreliable or the gap between the two plugs becomes too wide for a spark to cross. Each time your spark plugs spark, the high voltage electricity will minutely damage the metal tips of the plugs. Given time and mileage, this wear will steadily increase the fine-tuned gap the sparks have to span until the gap is too wide and successful sparking becomes intermittent or impossible.

Because of this, looking after your spark plugs is vital. Traditional spark plugs need replacing every 30-50,000 miles. High performance spark plugs tipped with the precious metals previously mentioned, however, can last between 80-100,000 miles. Either way, things still can go wrong, so never skip out on scheduled maintenance.

Common Symptoms of Spark Plug Failure

There are 4 main symptoms of spark plug failure that indicate it’s time to bring your Audi to the shop. We’ve listed these below to help you.

1. Lackluster Acceleration

To achieve punchy acceleration, your Audi needs extra ‘oomph’ from the engine. To do this the spark plugs need to fire more rapidly to provide the energy needed to go faster. Therefore, if your spark plugs are on the fritz, you’ll notice it getting harder to get your Audi to accelerate the way it should.

2. Low Fuel Efficiency

For your Audi to be as fuel-efficient as possible, it needs all its parts and systems to be working properly, particularly those inside the engine system. Poorly working spark plugs can increase fuel wastage, as they are unlikely to be able to produce a spark which burns up the majority of the fuel. They will instead leave fuel wasted and unburnt, which can lead to misfires, as discussed below.

3. Engine Misfires

Engine misfires occur when, for whatever reason, the fuel has not been ignited. This can be caused by failure of the spark plugs to produce the spark needed for ignition. It can also be caused as you drive by a spark plug which produces a small spark or an inconsistent spark. If you notice your car idling rough, it could be an indication that misfires are on the horizon.

4. Starting Struggles

Trouble starting your vehicle can be a clear indication that your spark plugs are failing. Of course, this can be caused by several other problems with your Audi, but as the spark plugs are the cheapest part to replace, it’s best to rule them out first before moving onto more costly parts.
