For car users
If your Peugeot 108's check engine light comes on, safely pull over and, if possible, check for immediate issues such as low oil or coolant levels, abnormal noises, or loss of power while maintaining a calm driving state. Then, prioritize scheduling a diagnostic scan at a trusted service center or dealership as soon as possible to identify and address potential engine, sensor, or emission system issues before they escalate.
Ignoring the check engine light
Ignoring the Peugeot 108's check engine light can lead to decreased fuel efficiency by up to 20%, increased harmful emissions, and rapid degradation of critical engine components such as oxygen sensors and the catalytic converter. Over time, this neglect may escalate minor issues into severe malfunctions that compromise overall performance and safety, ultimately resulting in expensive repairs and potential engine failure.
How to reset?
To reset the Peugeot 108 check engine light, disconnect the negative battery cable for about 10 minutes or use an OBD-II scanner to clear any stored fault codes, effectively rebooting the engine monitoring system. After the reset, run a diagnostic test and monitor for any recurring issues to ensure that underlying sensor or system faults are properly addressed.
A diagnostic check for a Peugeot 108's check engine light typically costs between $75 and $150, which helps pinpoint issues such as sensor malfunctions or emission system faults. Depending on the diagnosis, repair costs can range from an additional $100 up to around $500 or more if major components like the catalytic converter or engine parts need replacement.
Future prevention
Regular maintenance is key: regularly change the oil, check and replace air filters, and ensure that sensors and emissions systems are inspected as per Peugeot's service schedule to prevent the check engine light from activating. Prioritizing data-driven care such as using high-quality fuel and promptly addressing diagnostic trouble codes helps maintain optimal engine performance and reduces the likelihood of system errors lighting up the dashboard.
