What does the fuel refill indication on the Volkswagen CC dashboard mean?

The fuel refill indication on the Volkswagen CC dashboard is a reminder for the owner to refuel. Refueling precautions: Do not wait until the fuel warning light comes on to refuel, and do not fill the fuel tank to full capacity. Do not wait until the fuel warning light comes on to refuel: The fuel pump is located inside the fuel tank and operates at a high temperature during continuous use. Being submerged in fuel helps to effectively cool it down. When the fuel warning light comes on, it indicates that the fuel level is already below the fuel pump. If you always wait until the light comes on to refuel, it will shorten the lifespan of the fuel pump. Having too little fuel or running out of fuel may also cause the fuel pump to burn out. Do not fill the fuel tank to full capacity: For regular city driving, there is no need to fill the fuel tank to full capacity. A full fuel tank increases the engine load, which in turn increases fuel consumption.
As a seasoned Volkswagen driver of ten years, let me tell you: when the dashboard shows 'Refill' warning, it's 80% likely due to low engine oil! Volkswagens love to signal this way, especially turbocharged models like the CC. You should pull over immediately to check. Find a level spot, turn off the engine and wait 5 minutes, then pull out the dipstick, wipe it clean and reinsert to check the level. If it's below the minimum mark, grab a bottle of 0W-40 or 5W-30 oil and add about half a liter. Once I got this warning on the highway - bought oil at a service area for emergency refill, only to find next day that the oil pan was cracked and leaking. Remember never to keep driving forcefully - replacing a burnt turbocharger could cost you two smartphones!
Don't panic when you see this warning. Focus on checking three key areas: whether the oil level is below the minimum mark, if the oil pressure sensor is giving false readings, or if excessive oil consumption due to burning is occurring. Last time, I got the warning just 3,000 km after an oil change – turned out they didn't fill enough during servicing. With AC use in hot weather increasing engine load, consumption can be higher than in winter. If it happens right after an oil change, it's likely a leak – check for oil stains under your parking spot. Turbocharged (T) engines especially benefit from keeping a spare oil bottle in the trunk, particularly for older vehicles.
