Can I still drive if the coolant warning light comes on in my Volkswagen?

It is best not to continue driving. Detailed analysis is as follows: 1. Insufficient coolant: If the warning is due to insufficient coolant, you should not continue driving. If you do not have coolant available for immediate replenishment, you can add an appropriate amount of purified water, preferably soft water, such as distilled water. However, do not use hard water like tap water, and do not add too much, as it may alter the boiling point of the coolant. 2. Overheating: If the warning is due to overheating, you must not continue driving. Continuing to drive may cause the engine temperature to rise further, leading to engine damage. To avoid unnecessary losses and for safety reasons, you should not continue driving.
That day I was driving my Golf on the highway when suddenly a red warning light came on, so I quickly pulled over and turned on the hazard lights. Never ignore a coolant warning—overheating can cause engine seizure in minutes! I popped the hood to let it cool down and checked the overflow tank. If it’s empty, there’s a leak; if it’s full, maybe just a faulty sensor. Always keep distilled water in the car for emergencies—mineral water leaves scale. Once, a buddy of mine ignored it and drove two more kilometers, ended up with an 8,000 RMB repair bill. The tow truck only cost 200—what a waste!
