I have noticed that my Audi A2 has been using more fuel than usual, even though I have been driving the same routes and using the same driving habits. What could be causing this decrease in fuel efficiency?
ReplyOne possible reason for the decrease in fuel efficiency could be an issue with the engine's oxygen sensor. It may be malfunctioning and not providing accurate readings, causing the engine to use more fuel than necessary.
Have you checked your tire pressure lately? Low tire pressure can also cause a decrease in fuel efficiency. Make sure your tires are properly inflated for optimal fuel usage.
