Vehicle Diagnostics
ECU Scanning, Fault Code Diagnosis & Electrical Fault Finding

Find the Problem First Time
Salisbury, Adelaide
A warning light on the dash is your vehicle telling you something needs attention. But reading a fault code is only the start — the real work is understanding what triggered it, why, and what needs to happen next. That takes proper equipment and proper experience.
At Stealth Installs, we run genuine VAG diagnostic equipment alongside professional-grade scan tools, giving us deep access across engine, transmission, ABS, airbag, and body systems. Whether it's a persistent warning light, an intermittent misfire, or a pre-purchase check, we'll find the answer — not just the code.
