Why is my Audi A5 displaying a 'Glow Plug' warning light?

I recently noticed that my Audi A5's dashboard is showing a 'Glow Plug' warning light. What could this mean and how can I fix it?

The glow plug warning light typically indicates a malfunction in the glow plug system, which is responsible for starting your car's engine. This could be due to a faulty glow plug, a bad glow plug relay, or a wiring issue. I suggest bringing your car to a professional mechanic to diagnose and fix the issue. It's important to address this issue as soon as possible, as it can lead to further engine problems if left unattended.

If you have recently changed your car's battery, it's possible that the 'Glow Plug' warning light is simply a result of a reset in the car's system. Try driving your car for a few miles to see if the light goes off. If it doesn't, then it's likely a more serious issue and you should bring your car to a mechanic for further inspection.
