Removing Late 944 (1985.5 and newer) Gauge Cluster – 2.5L NA

Overview

This procedure outlines the steps to remove the gauge cluster from a Porsche 944 (8-valve engine configuration variants, 1985.5 onwards). The gauge cluster houses critical instruments like the speedometer and tachometer, and removing it is necessary for repairs, bulb replacements, or upgrades. This guide is specific to the 1985.5 and newer models, which have a different dashboard and trim design compared to earlier 944s. Follow these steps carefully to avoid damaging the delicate ribbon circuit board on the back of the cluster.

Tools Required

• Phillips screwdriver (stubby recommended for tight spaces)
• 24mm (15/16 inch) socket and ratchet
• Scribe, paint pen, or brightly colored nail polish

Step-by-Step Procedure

Step 1: Remove the Steering Wheel

1. Pry off the horn button from the steering wheel and disconnect the electrical spade connector on the back.

For 85.5 Onwards models:

• The horn button is centrally located and may require gentle prying with a flathead screwdriver to pop it off.

2. Using a 24mm (15/16 inch) socket and ratchet, remove the steering wheel retaining nut and washer. Set them aside in a safe place.

3. Mark the orientation of the steering wheel to the steering shaft using a scribe, paint pen, or nail polish. This ensures proper alignment during reassembly.
4. Pull the steering wheel straight off the steering shaft. Store it safely to avoid damage.

Step 2: Remove the Gauge Cluster Trim

5. Locate and remove the three Phillips head screws on the top of the plastic trim piece surrounding the gauge cluster. Use a stubby Phillips screwdriver for easier access in the tight space.

6. Remove the two Phillips head screws threading into the trim piece from the bottom, located on either side of the steering column.

7. Remove the Phillips head screws securing the vents in the center of the dash, which are part of the trim piece:

• One screw is in the vent area to the far right of the gauge cluster.

• Two screws are in the vent area closest to the gauge cluster.

8. Lift the bottom edge of the trim piece behind the steering column to clear the column trim. Gently pull down on the top of the trim piece to release it from the dash.
9. Slide the trim piece out of the dash. Move it carefully to avoid scratching the dashboard or damaging the vents.

Step 3: Remove the Gauge Cluster

10. Locate the four Phillips head screws securing the gauge cluster to the dash. Remove these screws and set them aside.

11. Slide the gauge cluster forward to access the electrical connectors on the back. Move it slowly to avoid catching the ribbon circuit board on the dash edges, as it can tear easily.

12. Disconnect the three electrical plug connectors on the back of the cluster:

• Each connector has locking levers. Push outward on the levers to release and remove each connector.

13. Slide the gauge cluster out of the dash. Tilt it slightly and pull one end out first if needed. Push up on the dash opening to create clearance if the cluster is tight.

For 85.5 Onwards models:

• Be extra cautious with the ribbon circuit board, as it is more exposed on these models and prone to damage.

Step 4: Reinstall the Gauge Cluster

14. Reinstallation is the reverse of removal. Slide the gauge cluster back into the dash, aligning it carefully to avoid damaging the ribbon circuit board.
15. Reconnect the three electrical connectors, ensuring the locking levers snap into place.
16. Secure the gauge cluster with the four Phillips head screws.
17. Slide the trim piece back into place, ensuring it fits over the steering column and vents. Secure it with the three top screws, two bottom screws, and three vent screws.
18. Align the steering wheel with the marked orientation on the steering shaft. Install the retaining nut and washer, tightening to 45 Nm (33 ft-lbs).
19. Reconnect the horn button’s electrical spade connector and press the horn button back into place.

Post Procedure Checklist

• Check that all screws are securely tightened and the trim piece is flush with the dash.
• Verify that the gauge cluster functions properly (e.g., speedometer, tachometer, and warning lights).
• Test the horn to ensure the button is correctly connected.
• Inspect the steering wheel alignment by driving a short distance, approximately 0.5 miles (0.8 km), to confirm it tracks straight.
• Ensure no warning lights remain on and no rattling noises come from the dash.
