Warning light or reduced performance
A complete scan and directed tests are needed before parts are proposed.

The 997 spans two production phases and includes Carrera, Turbo and GT models with materially different engines and transmissions. Its age makes history, previous repairs, seals, hoses, mounts and chassis condition as important as mileage.
Coverage
Model-specific systems
Carrera, Turbo and GT engine families must not be treated as interchangeable; oil, cooling and diagnostic concerns differ.
997.1 may use Tiptronic while 997.2 introduced PDK; manual clutch and linkage form a third path.
PASM equipment and ageing mounts, dampers, bushes and bearings all influence ride or warning symptoms.
Age, front-radiator debris and hose or housing condition deserve inspection without declaring universal failures.
Steel and optional PCCB systems require different condition assessment.
Earlier network architecture still needs stable voltage and complete fault capture before codes are cleared.
