Low Oil Pressure Light

What does the low oil pressure warning light do and why is it on?

The Low Oil Pressure Warning light is a warning light that can illuminate on your gauge cluster to warn you that the engine has lost engine oil pressure. When this happens, significant irreversible damage can be caused to your engine. Immediately pull over, and turn off the vehicle as soon as possible to limit the damage. You may also notice an engine knock due to low oil pressure.

Common reasons for this to happen

  • Low engine oil level
  • Low engine oil pressure
  • Clogged oil filter
  • Engine oil to thick or too thin
  • Faulty oil pressure sensor
  • Worn oil pump
  • Worn engine bearings

Can I drive with the low oil pressure warning light on?

The short answer is, no. You can check some basic things we will cover in the next section, but continuing to drive without knowing exactly why the low oil pressure light is on can cause serious engine damage.

How do I fix a low oil pressure warning light?

  1. Check the engine oil level and top it off if it’s low.
  2. Change the engine oil and filter; make sure to use the correct oil viscosity for your vehicle
  3. Using an engine oil pressure gauge check the actual engine oil pressure
  4. If it is low, replace the Oil pump/Oil pressure, regulator
  5. If it is the correct pressure, consider replacing the oil pressure sensor.

I had an oil leak and took my car to a BMW center. They said it was a leak in the oil filter
housing gasket. So I had it repaired ($1440.00) However 2 months later it is leaking again.
I added another quart of oil for now. Your list of possible reasons as to what it might be
is helpful. Not sure what to do next though.
Any suggestions – as the idiot light is still on.
Thanks
