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.

Gauge Cluster Printed Circuit Replacement.
The LutzAuto Instrument Cluster Printed Circuit Board Replacement is a precision-engineered solution designed to permanently correct common electrical failures in the Porsche 928 instrument cluster for model years 1985–1988.
From the factory, these clusters relied on a flexible printed circuit foil mounted behind the gauges. Over time, heat exposure, age-related material degradation, and repeated handling cause the original foil to become brittle, crack, or lose conductivity. This results in erratic gauges, failed warning lights, flickering illumination, and intermittent or total cluster malfunction. Repairing the original flex circuit is rarely reliable or long-lasting.
This LutzAuto replacement eliminates those issues by replacing the fragile flex foil with a modern, rigid printed circuit board (PCB). Manufactured to exact OEM dimensions and electrical specifications, the board restores stable power distribution and signal integrity to all gauges, warning indicators, and cluster lighting while dramatically improving durability.
Designed as a direct-fit replacement, this installs into the original instrument cluster housing with no permanent modifications required. It preserves the factory appearance of the dashboard while delivering modern electrical reliability—making it ideal for restorations, daily-driven classics, and preventative maintenance alike.
