With utmost care :)
Your oil light comes on when the OIL PRESSURE is too low ( your engine oil LEVEL may be O.K. )
The security light might come on while you are driving because it has a motion detector on it and when it senses the cars movement the light comes on.
depending on what your driving one eighth of a tank is left in the tank when your indicator light comes on
It means you have low oil pressure. Notice the light is red. Red means stop driving the car until this is repaired. Check the oil level and if it is full seek professional help.
its for traction
If the engine oil level is at the full mark, the light is not suppose to come on when driving.
water level sinsor defective
Check your coolant level it is probably low.
This could mean that your car is due for service , on the Sharan 1.8t the oil light needs to be reset after service, you find the reset plug to which you connect the device to reset the light under the ash-tray. Or, it coud that the oil pump is mulfunctioning, there is not enough system oil pressure.
If the oil level is fine, your oil level sensor or the sensor wiring is malfunctioning. Same for the ABS system. Check ABS fuses.
