Gauge Cluster Printed Circuit Replacement.
The LutzAuto Instrument Cluster Printed Circuit Board Replacement is a precision-engineered solution designed to restore reliable electrical function to the Porsche 928 instrument cluster used on later production models. This component replaces the original factory flexible printed circuit foil, which is a well-known weak point on aging 928 dashboards.
Over time, the original flex circuit becomes brittle due to heat exposure, material fatigue, and repeated removal during servicing. Cracks, broken traces, and poor conductivity lead to erratic gauges, failed warning lights, and unreliable cluster illumination. Repairing the original foil is rarely durable or effective.
This replaces that fragile foil with a modern, rigid printed circuit board (PCB) manufactured to precise OEM dimensions and electrical specifications. This upgrade restores consistent power delivery and signal integrity to all gauges, warning indicators, and backlighting while dramatically improving long-term reliability.
Designed as a direct-fit replacement, the board installs into the original instrument cluster housing without permanent modification, preserving the factory appearance while eliminating a major source of electrical failure. This makes it an ideal solution for restorations, preventative maintenance, or repairing persistent dashboard issues on Porsche 928 models.

Fits:

  • Porsche 928 4.5L 1982
  • Porsche 928S 4.7L 1982-83
  • Porsche 928S2 4.7L 1984

What This Product Does:
  • Replaces the factory flexible printed circuit foil
  • Restores stable electrical connections to all gauges and warning lights

About Instruments

Porsche Instruments & Gauge Clusters | Precision Monitoring for Performance and Reliability

Your Porsche’s instrument cluster is the heartbeat of the driving experience — delivering vital performance and engine data at a glance. From speedometers and tachometers to oil pressure and temperature gauges, these instruments combine precision engineering with timeless Porsche design. Over time, however, electrical faults, fading displays, or worn mechanisms can affect accuracy and reliability.

At Design911, we supply high-quality instrument clusters, gauges, and individual components designed to match or exceed original performance standards. Each part is meticulously engineered to ensure accurate readings, seamless integration, and long-term durability, restoring the driver-focused feel that defines every Porsche.

Whether you’re restoring a classic 911 cockpit or replacing a modern digital cluster, our range provides precision, authenticity, and performance you can trust.

What Do Porsche Instruments Do?

Instrument clusters and gauges allow drivers to monitor essential performance metrics, helping maintain control and awareness in all driving conditions.

Core Functions:

  • Display vehicle speed, RPM, fuel level, oil pressure, and temperature.
  • Provide real-time engine and system monitoring.
  • Integrate warning lights and indicators for safety and diagnostics.
  • Maintain Porsche’s signature driver-focused layout.
  • Enhance cabin aesthetics with precision-crafted design and finishes.

A properly functioning instrument cluster ensures both performance accuracy and a refined interior presentation.

Why Do Instruments Wear or Fail?

Even high-precision instruments are subject to wear, ageing, and electrical issues — especially in classic and high-mileage Porsche models.

Common Causes of Failure Include:

  • Faulty sensors or electrical connections causing inaccurate readings.
  • Dimming or failed backlighting and displays.
  • Internal gear or stepper motor wear in analogue gauges.
