How do I fix the low fuel consumption issue on my Audi A2?

I have noticed that my Audi A2 has been consuming less fuel than usual. This is causing frequent stops at the gas station and a decrease in overall performance. What can be causing this and how can I fix it?

The first thing to check is your fuel injectors. They may be clogged or malfunctioning, causing improper fuel delivery. I recommend getting them cleaned or replaced by a professional.

Another common issue is a faulty oxygen sensor. This can cause incorrect fuel-to-air ratio and result in decreased fuel efficiency. Have your mechanic check and replace it if necessary.
