What Does It Mean When Your VW Tiguan Says 'Engine on due to system/power needs'?

Riding your VW Tiguan is pleasurable until you see an “Engine On Due to System/Power Needs” notification appearing or blinking on the dashboard. Now, what does this indicate, and why does it appear? All these queries might be hitting your mind, making you a bit worried. Okay, calm down! Let’s analyze it more in detail.

What causes this message to pop up on your VW Tiguan’s dashboard?

Usually, this notification indicates your VW Tiguan needs the engine active to maintain power for essential functions. It’s typically associated with the start-stop system, which helps minimize fuel usage and emissions while idling at stops. Mentioning below the reasons behind turning on the “Engine On Due to System/Power Needs” notification:

 Insufficient battery charge: When the battery becomes weak over time, and its power drops too much, the engine stays active to recharge it. This makes the other electrical components, such as lights, AC, and infotainment systems, operate seamlessly.

 Increased power usage: If you turn on power-draining features like heated seats, rear defroster, or air conditioner, this might trigger the message. Because your car understands that these systems require some extra power, and as a result, the engine keeps running to meet the need.

 Climate control requirements: Your car cabin temperature should match where you set it. If not, the engine may stay on to assist the climate system in reaching the desired temperature to achieve your comfort.

 Engine start-up: During cold weather, the engine might have to remain on to ensure proper temperature for optimal performance and to keep you warm.

What might trigger this notification to appear frequently on your VW Tiguan’s display?

 Weak or old battery: With an aged or weak battery, the engine may often remain on to charge it constantly, as the battery is incapable of holding a charge.

 Poor sensors: Modern vehicles like VW Tiguan use sensors in the start-stop system so that it can monitor when the engine turns off or on. Thus, even a single faulty sensor might misinterpret the situation and send wrong data to the engine, insisting it stays on unnecessarily.

 Harsh weather conditions: Intense temperatures, like extremely hot or cold, can cause the engine to stay turned on for a longer period to help the heating or cooling systems manage your car's cabin temperature or keep the battery charged.

 Heavy use of features: If you use too many car features simultaneously, like charging devices, using the defroster, and turning up the volume on the stereo, it might put a strain on the system.

What actions you must follow to resolve it?

 Inspect the battery: If the battery is older than 3-5 years, it should be replaced. Consult with a certified technician to test whether the battery holds charge properly. If not, replacement is the only option left to fix the issue.

 Switch off unnecessary systems: One of the most usual ways to avoid this trouble is to turn off energy-draining features like the rear defroster and heated seats when you are not using them.

 Visit a technician: Even after performing the above steps, if you still notice the same notification appearing on the dashboard, then it's better to visit the nearest VW service center and seek professional assistance to inspect the troubleshoot key components, including sensors, alternator, and start-stop system. Plus, repair or replace the faulty one with a new, high-quality part suitable for your VW Tiguan.

 Pay attention to the weather: One thing you must be aware of is the extreme weather conditions, as it might trigger this message. After all, at that time, your car runs more intensively to balance comfort and mechanical needs.
