What should I do if my Audi A2's engine is making a strange noise?

I've noticed that my Audi A2's engine has started to make a strange noise. It's not a constant noise, but it's noticeable when I accelerate or when I start the car. What could be the cause of this and what should I do?

There could be a few potential causes for this noise, Jessica. One possibility is that your engine oil may be low or old, causing the engine to run less smoothly. You can check your oil level and if it's low, top it up with the recommended type of oil for your Audi A2. Alternatively, it could be an issue with the spark plugs or a belt that is loose or worn. In either case, it is best to take your car to a mechanic for a proper diagnosis and repair.
