A technician plugs professional diagnostic equipment into your car's OBD port, reads all stored fault codes, checks live data from sensors, and provides a detailed report with recommended fixes.
Absolutely — a pre-purchase diagnostic can reveal hidden issues like pending engine faults, airbag problems, or mileage discrepancies that aren't visible on a test drive.
Yes, but clearing the light without fixing the underlying fault means it'll come back. A proper diagnostic identifies the root cause so it can be fixed permanently.
A basic code reader shows fault codes. Full diagnostics includes live data, freeze frame analysis, component testing, and can access all vehicle systems — not just the engine.
Many issues can be fixed on-site — sensor replacements, wiring repairs, software updates. If workshop work is needed, your technician will explain what's required.
Most diagnostic providers cover all major makes. Some specialise in specific brands (BMW, Mercedes, VAG). Check the provider's profile for their coverage.
