It’s a question we hear almost daily and, with cars becoming more and more ‘intelligent’, it’s not surprising. The sight of an engine check light appearing on your vehicle’s dash is enough to throw your day into disarray. But what do they mean? We’ve highlighted the more common ones we see.
Oil pressure light
This light tells you when your engine has no oil pressure. It should never be on when your engine is running. If it comes on while driving, pull over and turn off the engine immediately, or risk terminal engine damage.
Battery light
If this light comes on when driving this could be a sign that your alternator or something else in the charging system has failed. You can drive for a limited amount of time, but eventually the vehicle will stop, as the battery will not be charging and will eventually run out of power. Turning off all unnecessary electrical components, such as the stereo or fans, will help save battery power.
Brake warning light
This light serves many purposes; from telling you that your park brake is on, warning you that your brake pads are getting low, your brake fluid is low or your ABS (anti-lock braking system) is faulty. If, after you’ve released your handbrake, this light remains on, we’d recommend a visit to your mechanic as soon as possible.
The dreaded engine check light
This light will always appear when you turn the ignition on. Once the engine is running and the ECU (engine control unit) has performed its self-checks, it should go out. However, if this stays on it could be one of more than a myriad of faults. The vehicle will require a diagnostic scan to determine the cause. Most modern workshops today should be well equipped to give you an accurate diagnosis.
Service reminder light
Don’t confuse the engine check light with your service reminder light, which is set to remind you that your vehicle is due for its next routine service. Maintaining regular servicing will lower your chances of any of the above lights coming on and throwing your day into disarray!
