Why is the speedometer on my VW Golf not working?
If your Volkswagen Golf’s speedometer is not working, it’s usually going to be caused by an issue with the VSS (vehicle speed sensor), or a bad ECU. The VSS is usually not very expensive, and they are not that difficult to replace.
What does the ECU do on a Volkswagen Golf?
Here’s a great guide on how to diagnose a wiring short in almost any vehicle ECU – Your Golf’s Engine Control Unit (ECU for short) is the computer that takes all of the information that the vehicle sensors compile and uses it to control the vehicle systems, and sends important vehicular telemetry data to the driver via the instrument cluster.
What does the VSS do on a Volkswagen Golf?
The VSS is one part of a system of sensors that helps keep you safe (traction control, ABS, cruise control). A modern vehicle’s speedometer takes the input from the Vehicle Speed Sensor and sends that data to the ECU. The ECU is programmed with your Golf’s gear ratios and stock tire height.

What does automatic transmission speed sensor do?
A transmission speed sensor calculates the transmission gear ratio when in use. A car has two speed sensors: the ISS and the OSS, working together to show the transmission data to the car's powertrain module. The ISS sensor monitors the input shaft's speed.
How do I know if my speed sensor is working?
Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor's wire coupling. Using the multimeter's voltmeter connect the probes to the ground and reference wires in the connector. If no voltage is received, the sensor is faulty.

What is a speedometer on a golf?
A modern vehicle’s speedometer takes the input from the Vehicle Speed Sensor and sends that data to the ECU. The ECU is programmed with your Golf’s gear ratios and stock tire height. It combines this data to send the speed reading to the instrument cluster. The causes of a bad speedometer will typically be found in these four things:
What is the connection between the drivetrain and the speedometer?
Vehicles used to use a cable that would usually run from the tail shaft of the transmission to the speedometer. There was a physical/mechanical connection between the drivetrain and the speedometer. Instead of this direct connection, a modern vehicle uses the vehicle speed sensor and relays that information to the speedometer.
