Why does my Audi A6 engine keep overheating?

I recently purchased a used Audi A6 and have noticed that the engine tends to overheat quickly, even on short drives. What could be causing this issue and how can I prevent it?

I encountered a similar issue with my Audi A6 and discovered that it was due to a faulty radiator. It's important to regularly check and maintain your radiator, as any blockages can lead to engine overheating. My advice would be to have your mechanic inspect the radiator and replace it if necessary.
