Changan CS75 PLUS: Persistent A/C smoke odour after smoking inside the vehicle

Symptoms

  • Smoking occurred with air recirculation selected, followed by a persistent smoke odour from the A/C. [1]

Possible causes

  • The manual explicitly states that smoke and tar deposited on the evaporator can cause a persistent odour. [1]

Checks

  • First check whether smoking occurred with air recirculation selected; have a qualified technician inspect the evaporator for contamination as needed. [1]

What to do

  • Have a qualified technician clean according to the contamination found; do not directly conclude from the odour that the evaporator leaks or must be replaced. [1]

Applicability and limits

  • Only applies to the corresponding CS75 PLUS configuration in the Russian-language CS75plus manual from the official Russian website, revised June 2024; the manual date is not treated as an applicable model year. No actual vehicle model has been linked. Do not extend to vehicles with the same model name, other powertrains or other markets. Scope: unknown [1]
  • Only applies to the smoking-related contamination explicitly described by the source; it does not explain all A/C odours.
