MG ZS: Red coolant temperature warning light flashing

MG ZS: Red coolant temperature warning light flashing

Symptoms

• The coolant temperature warning light is flashing. ^[1]

Possible causes

• This version of the manual explicitly identifies flashing as an indication of a coolant temperature sensor fault, separately from a steady light indicating high temperature. ^[1]

Checks

• Distinguish flashing from steady illumination precisely, stop safely and switch off the engine, and have a repair provider investigate faults related to the temperature sensor. ^[1]

What to do

• This entry only applies to this version's warning light definitions; do not replace the sensor before testing or apply this to other ZS model years. ^[1]

Applicability and limits

• Only applies to the English manual from the official European website and to the corresponding ZS configuration among the combustion-engine configurations described; the manual date is not treated as an applicable model year. No actual vehicle model has been linked. Do not extend to models with the same name, other powertrains or other markets. Scope: unknown ^[1]
• Only applies to the specific configuration in the cited manual; do not assume applicability to all vehicles with the same model name
