    Car diagnostics and inspection in Montreal

    A diagnostic is how you find out what is actually wrong before paying to fix it. That matters most in two situations: a warning light with no obvious symptom, and a used car you are about to buy.

    What this covers

    • Check Engine Light
    • Pre-Purchase Inspection
    • Noise / Vibration Diagnostic
    • Safety Inspection

    Signs you may need this

    • A check engine light, or any warning light you do not recognise
    • A noise, smell or vibration you cannot place
    • You are about to buy a used car and want it inspected first
    • A problem that comes and goes and has not been pinned down
    • You want a full condition report before a long trip

    How often it's needed

    Diagnostics are done as needed rather than on a schedule. A pre-purchase inspection is worth doing on any used car before money changes hands — it is the cheapest step in the entire transaction and the one most often skipped.

    Quebec context

    A pre-purchase inspection matters more on a Quebec car than in most places, because road salt causes corrosion that is invisible until you look underneath. Ask specifically for the underbody, brake lines and subframe to be inspected.

    What affects the cost

    • Scan-tool read versus genuine diagnostic time
    • How reproducible the fault is — intermittent problems take longer to find
    • Depth of inspection, from a basic multi-point to a full pre-purchase report
    • Whether disassembly is needed to reach the suspect component
