In this article, we will explore the causes of oil consumption in the 2004 Audi S4 and provide some solutions to help you fix the problem.

What Causes Oil Consumption in the 2004 Audi S4?

There are a few different factors that can contribute to oil consumption in the 2004 Audi S4. One of the most common causes is a faulty piston ring.

If the valve is clogged or damaged, it can cause oil to be drawn into the combustion process and burned up in the engine. This can lead to increased oil consumption and other engine problems.
