The most common reason for the orange light with a spanner symbol to appear is low engine oil. If the oil level is low, the engine will not be properly lubricated, which can cause serious damage. Check the oil level using the dipstick. If the oil level is low, add oil until it reaches the "full" mark on the dipstick.
Check the Oil Pressure
If the oil level is okay but the orange light is still on, the oil pressure may be low. This can also be caused by a faulty oil pressure sensor. To check the oil pressure, you can either use a manual oil pressure gauge or use the oil pressure sensor on the engine. If the oil pressure is too low, it is best to stop the engine and take it to a mechanic.
Check the Coolant Level
Another reason for the orange light with a spanner symbol to appear is low coolant. Coolant is responsible for keeping the engine cool. If the coolant level is low, the engine can overheat, which can cause serious damage. Check the coolant level by looking at the coolant reservoir. If the coolant level is low, add coolant until it reaches the "full" mark on the reservoir.
Check the Brake Fluid Level
Low brake fluid can also cause the orange light with a spanner symbol to appear. Brake fluid is responsible for transmitting force from the brake pedal to the brake calipers. If the brake fluid level is low, the brakes will not work properly, which can be dangerous. Check the brake fluid level by looking at the reservoir. If the brake fluid level is low, add brake fluid until it reaches the "full" mark on the reservoir.
Check the Battery
Finally, the orange light with a spanner symbol can also be caused by a weak battery. If the battery cannot provide enough power to the ignition system, the engine will not start. Check the battery by looking at the terminals. If the terminals are corroded, clean them with a wire brush. If the battery is old, it may need to be replaced.
If you have checked all of these things and the orange light with a spanner symbol is still on, it is best to take your car to a mechanic. They will be able to diagnose the problem and make the necessary repairs.
