Can I add a little oil when the oil light of the Audi car is on?

You can add oil. The reason for this phenomenon is insufficient pressure. Insufficient pressure: Because the oil pump is severely worn after long-term use, the gaps between various components are large. When the engine speed is low, the oil becomes thinner when the engine is hot, resulting in the oil pressure failing to reach the value specified by the manufacturer, causing the oil light to alarm. When the engine is cold, the oil viscosity is higher, and the oil leaks less in the gaps of the oil pump components, so the oil pressure can reach the value specified by the manufacturer, and the oil light will not come on. Solution: It is recommended that you check the oil pump failure as soon as possible. If it is used for a long time, it will cause severe engine wear. When repairing the oil pump, you should also check the oil pressure and whether the oil passages are blocked.
The other day, I was driving my Audi A4 when suddenly the oil warning light came on, which scared me so much that I immediately pulled over and turned off the engine. My experience tells me that when this light comes on, you can't just top up the oil and call it a day—you must first check the oil dipstick to confirm the oil level. If the level is low, you can add some oil of the same specification, but if the light stays on after adding oil, don't drive any further. It's most likely an oil pump failure or a faulty sensor. Last time, a friend of mine ignored it and kept driving, only to end up with a seized engine that cost over 30,000 yuan to repair. Audis are particularly sensitive to oil, and mixing different brands can easily cause problems. If you're unsure, it's best to tow the car directly to an authorized dealership—don't risk major repairs just to save on towing fees.
