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.
