What Does an Audi 2001 TT OBDII Code Mean?

The “check engine” light is your car’s way of saying, “Hey, something’s not right!” But it doesn’t tell you what’s wrong. That’s where the OBDII code comes in. It pinpoints the issue, acting like a digital detective for your car’s health. Each code corresponds to a specific problem, ranging from emissions issues to faulty sensors and even transmission troubles.
