Do You Need an Engine Diagnostic?

If your vehicle is exhibiting any of the following symptoms, it’s time to bring it to Peter Jones for an expert diagnostic check:

  • Illuminated Warning Lights: Especially the Check Engine Light (EML), ABS, or Airbag warning lights.

  • Performance Issues: Sluggish acceleration, stalling, or the engine going into “limp mode.”

  • Unusual Noises: Knocking, whining, or rattling sounds coming from the engine bay.

  • Poor Fuel Economy: Suddenly spending more on petrol or diesel than usual.

  • Rough Idling or Misfiring: The engine feels shaky when stopped or driving at low speeds.

  • Emissions Test Failure: Your vehicle is failing its required emissions or smoke test.
