Here's why it might be flashing:
* Extremely Low Oil Level: This is the most common cause. Check your oil level immediately using the dipstick. If it's low, add oil *only after the engine has cooled completely*. However, adding oil may only be a temporary fix; the underlying problem still needs addressing.
* Oil Pump Failure: The oil pump is responsible for circulating oil. A failing pump can't maintain sufficient pressure. This is a major mechanical failure requiring immediate professional attention.
* Clogged Oil Filter: A severely clogged oil filter restricts oil flow, leading to low pressure. Replace the filter, but again, this might mask a larger issue.
* Leaking Oil: A leak in the engine or elsewhere in the oil system can rapidly reduce oil level and pressure. Look for visible leaks under the car.
* Worn Engine Bearings: Worn bearings allow oil to escape, reducing pressure. This is a serious problem requiring engine repair.
* Oil Pressure Sensor Failure: While less likely to cause a *flashing* light (usually a steady light), a faulty sensor could give a false reading. However, given the seriousness of a flashing light, you should still assume a genuine low-pressure situation.
* Blocked Oil Pick-up Tube: This tube sucks oil from the sump into the pump. If it's blocked by debris, the pump can't draw enough oil.
What to do:
1. Pull over immediately and turn off the engine. Continuing to drive risks severe engine damage.
2. Check the oil level (after the engine has cooled).
3. Have the vehicle towed to a qualified mechanic. Do not attempt to drive it.
4. Do not add oil and restart the engine if the level is very low unless you can positively identify a leak and have a means of correcting the leak. If you add oil only to have it immediately leak out, you are wasting both money and time.
A flashing oil light is never something to ignore. Prompt professional attention is crucial to prevent costly engine damage.
