What does the exclamation mark on the Volkswagen steering wheel indicate?
2 Answers
The exclamation mark on the Volkswagen steering wheel is a symbol indicating that the EPS (Electric Power Steering) is not activated. Overview of EPS: EPS stands for Electric Power Steering system. The Electric Power Steering system represents the future direction of automotive steering systems. This system provides steering assistance directly through an electric motor, eliminating the need for components such as the hydraulic power steering pump, hoses, hydraulic fluid, drive belt, and engine-mounted pulley found in hydraulic power steering systems. This not only saves energy but also benefits the environment. Additionally, EPS offers advantages such as easy adjustment, flexible installation, and the ability to provide steering assistance under various conditions. Technical Advantages of EPS: In traditional hydraulic steering systems, the hydraulic pump operates continuously while the engine is running, increasing overall fuel consumption by 3% to 5%. In contrast, EPS relies on the battery as its energy source and uses an electric motor as the power component, allowing it to operate independently of the engine. As a result, EPS consumes almost no engine fuel directly. Furthermore, EPS eliminates the issue of hydraulic fluid leakage associated with hydraulic power steering systems. By utilizing electronic control, EPS produces almost no environmental pollution and further reduces fuel consumption.
I've also encountered the exclamation mark light on the steering wheel dashboard while driving myself, which could indicate a problem with the steering system, usually an electric power steering system failure, such as a broken sensor or an overheated motor. In this case, the steering wheel becomes heavy and less responsive. The last time my car had this issue was on the highway, and I immediately slowed down and pulled over to check. Fortunately, it turned out fine, and later at the 4S shop, replacing a sensor fixed the problem. I suggest that when you encounter similar issues, don't rush to keep driving because steering failure is very dangerous. Get it checked and handled by professionals as soon as possible to avoid accidents on the road. Also, pay more attention to the condition of the steering fluid or electronic systems during regular maintenance.
