How do I fix the speedometer on my Audi 80?

I recently noticed that the speedometer on my Audi 80 stopped working. What could be causing this issue and how can I fix it?

The most common cause for a malfunctioning speedometer in an Audi 80 is a faulty speed sensor. I recommend checking the sensor and replacing it if necessary. Also, make sure to check the speedometer cable for any damage or disconnection.

Another thing to look into is the speedometer gauge itself. It could be damaged or worn out, which can cause inaccuracies or a complete stop in functioning. Depending on the severity, you may need to repair or replace the gauge.
