Oil light on when driving 190E Mercedes?

If the oil light comes on while driving a 190E Mercedes, it typically indicates low oil pressure, which can be caused by low oil levels, a failing oil pump, or a clogged oil filter. It's crucial to pull over safely and check the oil level immediately. Continuing to drive with the oil light on can lead to severe engine damage. If the oil level is adequate but the light remains on, have the vehicle inspected by a mechanic as soon as possible.
