Ferrari Portofino Speedometer Carbon 958584

the part number 958584 refers to the Carbon Fiber Instrument Cluster (Speedometer/Rev Counter) for the Ferrari Portofino.

This component is part of the high-end interior carbon fiber package and is most distinguished by the carbon fiber surround (binnacle) and the central analog tachometer, which is flanked by high-resolution digital displays.

1. Technical Identification

• Part Number: 958584 (This is the assembly for the main driver display).

• Components: * Central Tachometer: The analog dial, available in various colors (Giallo/Yellow, Rosso/Red, Bianco/White, etc.).

  • Dual TFT Displays: These flanking screens handle the speedometer, infotainment, and vehicle status (VDA – Vehicle Dynamic Assistance).

  • Carbon Fiber Surround: High-gloss carbon fiber housing that replaces the standard aluminum or plastic finish.

• Compatibility: Designed specifically for the Ferrari Portofino (F164). Note: The Portofino M may use a slightly different digital interface, though the physical housing is similar.

2. 2026 Market Pricing (Estimated USD)

Replacing an instrument cluster is a “software-locked” event, meaning the part cost is only half the battle; the rest is programming.

3. Common 2026 Issues & Failures

If you are looking for part 958584, you may be facing one of these common Portofino display issues:

• TFT Screen Flickering: The digital screens on either side of the rev counter can develop “dead pixels” or backlight failure over time.

• Sticky Buttons: The controls on the binnacle for navigating the menus can become “sticky” (a classic Ferrari plastic degradation issue), often necessitating the replacement of the surround or the whole unit.

• Odometer Synchronization: If the unit is replaced with a used one, the odometer will often flash or refuse to show the mileage until a “Proxy Alignment” is performed.

4. Installation & Programming

• Mileage Lock: In 2026, Ferrari’s security protocols are very strict. You cannot simply plug in a used cluster (958584) and have it work. The mileage is stored in both the ECU and the Cluster. If they don’t match, the car may enter a “Tamper Mode.”

• DEIS Programming: A new or replacement cluster must be programmed using the Ferrari DEIS diagnostic system to sync the VIN and the current mileage.

• Tachometer Color Swap: Some owners buy 958584 just to change the color of their rev counter (e.g., from Black to Yellow). This is a complex way to do it; specialists can often just swap the dial face for a fraction of the cost.
