How to troubleshoot low coolant level in an Audi A2?

I noticed that my Audi A2's coolant level is lower than usual. What could be causing this and how can I resolve the issue?

It is important to regularly check your Audi A2's coolant level, as it is crucial for keeping your engine from overheating. Usually, low coolant level is caused by a leak in the system. It is recommended to have a mechanic inspect your car to identify and fix any leaks as soon as possible to prevent any further damage.

If there are no visible leaks, it is possible that the low coolant level is due to evaporation. This is more likely to happen in hotter climates. In this case, simply refill the coolant to the appropriate level and monitor it regularly. If the issue persists, it is best to have a mechanic take a look.

Another possible cause of low coolant level could be a damaged or malfunctioning radiator cap. This can prevent the coolant from properly circulating and can lead to low coolant level. Consider replacing the radiator cap if it appears to be damaged or worn out to see if it resolves the issue.
