What should I do if my check engine light is on?
Understanding the Engine Light The engine light, also known as the "check engine light" or "malfunction indicator lamp" (MIL), is part of your vehicle’s onboard diagnostics system. It’s designed to alert you when the system detects an issue that could affect your car’s performance, emissions, or safety. In modern vehicles, the engine light is connected to a wide array of sensors and components that monitor everything from engine performance to exhaust emissions. When something goes wrong, the light comes on to alert the driver that it’s time to investigate. Assessing the Situation The first thing to do when the engine light comes on is to assess the situation. If the light is steady, it generally indicates a non-urgent issue, though it still needs attention. If the light is flashing, it’s a sign of a more serious problem that requires immediate action. A flashing engine light can indicate a misfire or a problem that could damage the catalytic converter if the vehicle continues to be driven. In this case, it’s important to pull over safely and turn off the engine as soon as possible.

What is engine diagnostics?
Engine diagnostics is a process that uses specialized tools to identify issues within your vehicle's engine. It helps pinpoint problems that may not be visible during a standard inspection.
How long do brakes last?
Brake pads typically last between 80,000 to 100,000 km, while brake rotors generally last from 100,000 to 120,000 km. However, this lifespan varies drastically depending on your vehicle model, driving habits (like aggressive stopping or towing), and whether you do mostly city driving (stop-and-go) versus highway driving.
What is a tune-up?
Historically, a tune-up referred to physically adjusting parts in an older car's ignition system—such as the distributor cap, rotor, and spark plugs—to keep the engine running efficiently. Because modern vehicles use computerized, distributor less ignition systems, opinions in the automotive community differ on its modern definition. Most mechanics and enthusiasts agree that a "tune-up" today simply refers to preventative routine maintenance rather than heavy mechanical adjustments.
How do I know if I need new tires?
You may need new tires if you notice uneven wear, or you notice physical damage like cracks and bulges or when the tread depth drops below 2mm the built-in tread wear bars are flush with the surface. In Australia, experts recommend replacing tyres once the tread hits 3mm to maintain optimal safety in wet
What are the signs of a bad battery?
Common signs of a bad battery include difficulty starting your vehicle, dimming headlights, and a swollen battery case. If you notice any of these symptoms, it's best to have your battery tested.
How often should I get my oil changed?
Change your engine oil every 10,000 km, or every 6 months, depending on your vehicle and driving conditions. Always follow the specific intervals outlined in your car's Owner's Manual Severe Driving Conditions: If you frequently tow heavy loads, drive in stop-and-go city traffic, idle for long periods, or operate in dusty/extreme climates, you should change your oil much more frequently—often cutting the recommended interval in HALF
