Your Audi can misfire for many reasons, from lack of fuel, poor ignition, or even stuck parts. Whatever the cause, it is important to never ignore misfires, as the problem won’t go away and will only get worse given time. Unless you’re technically minded, you’ll want to take your Audi to the professionals. You might wonder how they fix your misfiring engine. Below, we will take a look at some of the causes of engine misfires and discuss repair work needed to fix a misfiring engine.
The Check Engine Light
The first time you are aware that your Audi has engine trouble may be when you see the illumination of the check engine light. This warning light is a great safety feature which helps to protect the integrity of your car. It is also helpful for the professionals, too. The check engine light is triggered by your Audi’s onboard computer, the ECU. Along with triggering the light, it will also send out specific error codes which describe the nature of the problem. Using diagnostic equipment, mechanics can translate these error codes and get to the heart of the problem accurately and quickly.
Spark Plugs and Wires
The most common issue that can be fixed at home or by the professionals is the spark plugs. Spark plugs create the spark needed to ignite the air/fuel mixture inside the engine. These parts are very inexpensive to purchase, costing as little as $2. They can be swapped out in under an hour. In recent years, spark plugs have also been designed to last a lot longer than previous renditions, now only needing changing around every 80,000 to 100,000 miles.
A little more costly to replace are the spark plug wires. It’s often advised to replace these when you are replacing spark plugs, as you need to remove them to replace the spark plugs anyway. Depending on the make and model of your car, a set of new wires costs between $30 to $80.
The ignition coil is what gives the spark plugs their power. A strong indicator that the coils need replacing is when your Audi misfires, but it can also backfire, too. You can replace this part at home with a little know-how, but your mechanic can also do this for you quickly, and will probably inspect the health of your spark plugs and wires, too, as they are all part of an interconnected system. So, it’s best for the professionals to complete the job in its entirety to save you another trip back to the shop if you DIY repair these maintenance items a-la-cart style.
If you notice your Audi is running lean, then you can check for issues with your fuel injectors as well as keeping an eye out for a vacuum leak. You can find out if you have a leak by turning the engine on and listening for the hissing sound of escaping air. However, you’ll need to have your mechanic pinpoint the leak for you. To do this, they will use a smoke machine to find the precise location. It isn’t worth trying to patch a leak in the vacuum hose, as these parts are inexpensive to have replaced and will then give you the confidence of having a new hose.
Mechanical misfires usually occur in older cars. This term can apply to issues with a range of parts. A mechanic will need to have a good look at your engine to fully resolve the issue. You might have problems with a stretched timing chain, which needs a timing light to diagnose or even by using an engine stethoscope. Other problems could include gaskets, cylinders, or your crank or camshaft, too. So as you can see, with a mechanical misfire, there can be a lot of detective work needed.
Of course, as previously mentioned, error codes known as Diagnostic Trouble Codes (DTC) can also be read by your mechanic’s diagnostic equipment. This will help them to narrow down the likely cause of your problem and quickly fix the issue.
