How to Reset the Fault Light on a Bora?
2 Answers
To reset the fault light, you can either start and turn off the vehicle three times in a row or disconnect the negative terminal of the engine battery, wait for 30 seconds, and then reconnect it. If the fault light remains on after disconnecting the battery, it indicates that there is indeed an engine malfunction, and you should take the vehicle to a repair shop for diagnostics. If the fault light comes on while driving, maintain a low speed and continuously monitor the oil pressure gauge for any warnings. If the oil level is critically low, stop the vehicle immediately. Also, check the coolant temperature gauge (antifreeze) for any warnings. If a warning appears, do not continue driving. It is best to contact a repair shop and wait for assistance.
A few days ago when my Bora's malfunction indicator light came on, I first used a simple OBD diagnostic tool plugged into the port under the steering wheel and connected to a mobile app to read the trouble codes. If it showed common codes like P0171, it usually indicates potential intake system leaks or a dirty oxygen sensor. I checked the air filter and found it slightly clogged – after cleaning it and restarting the engine, the light turned off. However, sometimes the issue lies in the fuel system, such as dirty fuel injectors; in such cases, I'd run a tank with fuel additive on the highway. Remember, an illuminated warning light isn't trivial—it alerts to emissions or mechanical problems. Simply clearing the code without fixing the root cause may lead to greater damage. I make it a habit to perform regular self-checks with diagnostic tools to maintain vehicle health. If unfamiliar with the process, investing in a cheap Bluetooth OBD module (around tens of RMB) and following the app's step-by-step guidance works. Safety first—always confirm the issue is fully resolved after clearing the light before driving with confidence.
