Low Fuel Economy Due to Carbon Buildup in Audis

Audi Fuel Gauge

If you are an Audi owner, you want to take good care of your car. By making sure that all of the components in your car or working effectively, are in good health so to speak, are not presenting with any problems, you can make sure that everything else works to optimum capacity.

The Importance of Fuel Economy

Fuel economy is one of these areas that is very important. Your Audi is designed to provide you with very good fuel economy. That means the car should maintain a regular and efficient amount of fuel consumption for the amount of driving you do. Certainly regular things like speeding or aggressive driving might impact this level of fuel economy, but on average most Audi owners see that the rate of consumption remains more or less level throughout the lifespan of the vehicle so long as everything is in good working order.

But what if things are not in good working order? What if your vehicle stops performing properly? There are many different issues with a variety of systems that could contribute to poor fuel economy. If all other things seem to be working properly but your vehicle is no longer achieving the optimal level of fuel economy, there could be carbon build-up. The problem with carbon buildup is that it can reach many different components within multiple systems and if it’s not tracked early enough and removed it could cause a lot of expensive damage to your vehicle.

What Causes Carbon Buildup?

There are different issues with components like the fuel stratified injection engine in the Audis, which often have problems with engine carbon build-up. These engines are some of the first gasoline direct injection engines built by Audi. Problems with oil consumption might damage the top end of the engine, which can lead to carbon build-up when the oil begins to burn off. If you notice increased oil consumption in your vehicle or blue smoke coming from under the hood, it is wise to take your car in to be inspected. You might find oil within your air intake hose and leaking through the oil filler cap. The reason behind this would be a broken check valve on the intake manifold, preventing a proper seal which allowed oil leaks and carbon build-up.

Other carbon buildup issues could be caused by substandard oil, which can damage the engine and require your PCV check valve to be serviced. Low quality oils can also damage your high pressure fuel pump. In fact, excessive wear and tear on your camshaft lobes takes place when your high pressure fuel pump stops working properly, which is often because of improper oil. Excessive wear and tear on your camshaft lobes will force your pump piston lift to work harder than normal, which will cause fluctuations in the fuel rail pressure. Obviously the longer these issues persist, the more damage happens.

Each of these issues can result in carbon buildup, which makes your entire system less efficient and increases the amount of fuel your vehicle requires to operate.

Getting Repairs

It is important that you don’t let carbon build-up continue to Audi Carbon Buildup build up in your engine once you’re aware of the problem. This is something that should be removed so that your vehicle can go back to maintaining its regular fuel economy. The longer this issue is allowed to persist, the more buildup will accumulate in different components within the vehicle and the more damage you will see. Like many car problems, carbon buildup is one that will only compound with time, causing more and more issues, worse fuel economy, and further part failures.
