BMW Oil Light Reason & Meaning

The first thing to find out about the oil light is to ensure that it’s not a scheduled maintenance reminder. Depending on your vehicle, maintenance reminders may have similar warning lights and alarms. If you’re overdue for your last oil change, it will say ‘change oil now’. It’s not bad like an oil light but necessary to fix the problem.

Causes Of BMW Light Off:

If the engine is low on oil, the oil light may turn off. Some common causes of oil leaks are:

  • The oil filter was incorrectly replaced
  • Improperly sealed drain plug
  • The oil filler cap is damaged
  • Corroded gaskets

Additionally, if you aren’t a service technician you can see the oil leaks to pop the car hood. Your engine can be dirty but if you see a wet, and oily spot that means there is an oil leak. Adding the missing oil can be an easy task. But it eventually causes oil pressure if you are not corrected and the engine is damaged.

BMW Minimum Oil Level Warning:

If you get a notification from your BMW about the oil minimum warning level, your engine needs enough oil. And that means it’s time to add more oil.

Driving with low oil levels will damage your car’s engine, so it should be addressed right away. Fortunately, you can take your car to a mechanic to add the oil, or you can handle it yourself.

After doing that, If you want to add oil yourself, check your owner’s manual and find out what oil is best for your BMW and locate the oil cap. Then add oil by yourself and give it another to add the oil.

BMW Low Oil Symptoms:

If your BMW car runs out of oil, your engine will quickly seize up. Often you can’t fix it and you will need a full replacement. But if you are aware of common warning signs you can avoid this problem. Let’s see the symptoms of BMW low oil:

The light usually means low oil pressure instead of low oil level. Sadly it’s even worse, if you look it up it basically means “shut me down immediately I’m dying”.
