Not just a code

The case behind the recommendation.

In this Cruze demonstration, P0299 leads through reported findings to an intake manifold and camshaft cover recommendation—not straight to a turbo.

Edited Cruze test-case conversation showing reported PCV-system findings and an intake manifold and camshaft cover recommendation.

These real-case outcomes were reported by the shop, not independently or OEM verified. They are distinct from the simulated demonstrations above.

How it works

Keep the findings in view.

A clear path through the conversation. The technician performs the tests and owns the repair.

  1. Start with the vehicle.

    Enter the vehicle information, symptom and any codes. Give the Foreman the concern you need to work through.

  2. Work through guided checks.

    Enter findings and follow the next check. Techs who prefer Spanish can use Spanish in the diagnostic conversation.

  3. Make the repair.
    Verify the result.

    Use the recommendation alongside professional judgment and appropriate service information. Confirm the result after the repair.
