It is the engine malfunction indicator light of the motor vehicle. When this warning light illuminates, the motor vehicle must not be driven. Forcing operation may cause excessive wear to the engine, and in severe cases, lead to engine damage. A diagnostic scanner can be used to retrieve specific trouble codes for engine fault diagnosis. Relevant details are as follows: 1. Diagnosis required: When the engine malfunction indicator light comes on, it indicates certain faults in the vehicle's engine, which may result from various causes. Repairs should be conducted based on the specific symptoms. 2. Engine: The engine is a crucial component of the vehicle. If it malfunctions, the vehicle cannot operate normally. Apart from the engine malfunction light, the vehicle must not be driven when any warning light appears on the instrument panel.

I once encountered the situation where the Stop light came on while driving a Citroën. It was usually caused by low oil pressure or an overheating cooling system, possibly due to an oil leak or water pump failure. At that time, I didn't stop immediately, and the engine temperature soared to the limit, nearly causing it to be scrapped. The repair cost me several thousand. So, I suggest that if you notice the light on, pull over and turn off the engine right away, turn on the hazard lights, and check if the dashboard shows high water temperature or if the oil dipstick indicates low levels. Safety first—don't push through. Contact a professional repair shop to diagnose the issue. Regularly changing the oil and coolant can effectively reduce such incidents, and carrying a simple toolkit for emergencies while driving is also quite practical.

As a Citroën owner, the Stop light coming on is quite alarming. Last time I experienced it, the flashing light was caused by a braking system issue or battery charging fault – that moment was truly heart-stopping. After safely pulling over and checking the manual, I found it could indicate insufficient brake fluid or the alternator not charging. Never underestimate it, as delaying repairs can lead to more serious vehicle accidents. I always keep emergency numbers handy on my phone navigation and check brake pedal firmness when pulling over. Getting it inspected at an authorized 4S store is the most reliable approach – don’t tamper with electronic components yourself. During regular car washes, pay attention to any oil leakage traces under the chassis – prevention is always better than cure.

Common causes for the Stop light to illuminate include low engine oil pressure, overheating of the cooling system, or abnormal brake hydraulic pressure. In Citroën models, false alarms from the ECU sensor or circuit malfunctions may also trigger it, requiring immediate parking and inspection to prevent damage to core components. Once it occurs, it is recommended to first turn off the engine to confirm the fault type and proceed to the service center as soon as possible for repairs or part replacements such as the oil pump or thermostat.
