How do I fix the acceleration issue in my Audi A2?

I recently noticed that my Audi A2 is having trouble accelerating, especially when climbing hills or merging onto the highway. What could be causing this issue and how can I fix it?

It's possible that your fuel filter may be clogged, causing a decreased flow of fuel to your engine. Try replacing it and see if that resolves the issue.

Another potential cause could be a faulty throttle position sensor. This sensor helps regulate the engine's fuel and air mixture. If it's malfunctioning, it could be affecting your vehicle's acceleration.

Have you checked your spark plugs? Worn or dirty spark plugs can lead to a decrease in power and acceleration. Consider replacing them to see if it makes a difference.
