Instrument cluster (VW Golf 1)

Replacement

1. Before starting work on the instrument panel, be sure to disconnect the ground wire from the battery.

2. Remove the steering wheel (see chapter "Steering").

3. Remove the handles from the heater control levers.

4. Remove the heater control unit trim.

5. Press the decorative window plug to install the radio (with the radio installed, you must remove its front panel and control knobs - see chapter "Additional equipment").

6. Remove the screws securing the instrument panel frame and pull the frame into the passenger compartment (figure P:7).

Remove the indicator lights and switches from the instrument panel frame by releasing the clips and pushing each element towards the interior

8. Remove the instrument panel frame.

9. Remove the two screws securing the instrument panel (instrument cluster - Figure P:8).



10. Disconnect the speedometer cable from the back of the dashboard by squeezing the two plastic tabs together.



11. Disconnect the central connector and remove the instrument panel.

The instrument panel is installed in the reverse order of removal. Check the operation of all switches, signal lamps and instruments.

Voltage stabilizer - replacement

On cars manufactured before August 1975, the voltage stabilizer was built into the fuel level and temperature gauges. Since August 1975, the voltage stabilizer for the fuel level and temperature gauges has been installed as a separate device.

1. Remove the instrument panel as described previously.

2. Unscrew the stabilizer mounting screw, disconnect the wires and remove the voltage stabilizer (2, figure P:9).



3. Installation of the voltage stabilizer is carried out in the reverse order.

Printed circuit board - replacement

1. Remove the instrument panel and voltage stabilizer as described earlier.

2. Carefully remove the lamp holders from the sockets on the shield and the printed circuit board (1, figure P:9).

3. Loosen the nuts and screws securing the printed circuit board and carefully remove the printed circuit board from the instrument panel (9, figure P:9).

4. Installation of the printed circuit board is carried out in reverse order.

Speedometer replacement

Remove the instrument panel as described above.

1. Remove the printed circuit board and voltage regulator.

2. Remove the bolts of the carrier plate and instrument casing (if available) and remove the carrier plate and casing.

3. Loosen the speedometer mounting screws and remove it (4, figure P:9).

4. The speedometer is installed in the reverse order.

Replacing the tachometer and clock

Tachometer removal and installation procedure (if available) and the clock is similar to that described above for the speedometer.

Temperature indicator

If the indicator shows "HOT" ("high temperature" - the needle is in the red zone), make sure that there is no actual engine overheating due to a faulty cooling system (see chapter "Cooling system").

If the indicator always shows "COLD" ("low temperature"), this is due to a defect in the sensor, pointer or wiring.

Check the circuit using a test lamp with wires. To avoid damaging the temperature gauge, connect a 12 V, 6 W test lamp between the temperature sensor wire and the ground when checking. The sensor is located in the housing at the end of the cylinder head on the flywheel side.

Disconnect the wire from the sensor and connect a test lamp between the wire and the ground. If the pointer moves to the "NOT" zone, replace the defective sensor.

If the arrow remains in the "COLD" position, the device itself or its wiring is faulty. Removing the fuel level and temperature indicators is done in the same way as the speedometer.
