oil level sensor accuracy?

wba116i · 04-19-2018, 04:41 AM

this is my first BMW so please bear with me. i have a 2007 116i - Last week while driving back from another city 'low engine oil' sign popped up and it suggested to add 1L oil. I freaked out and stopped my car to check for any visible leakages (didn't find any). And the very next day in the morning before leaving for work - i checked the oil level and it said oil level OK (right in the middle of the gauge on the dashboard). I decided to take the public transport - being unsure of the oil level readings. The reason i freaked out was because i had a oil change 6 months ago (have driven 2k km since) - when i bought the car it had 166k on the meter and now its 168k.

So, i added 500ml oil yesterday and drove for about 10km and checked the level which showed 'FULL' (image 1). and at the end of journey (50km) - the oil dropped to 80-85%(image 2).

Whats happening here? I am freaking out. Should i be worried?

Hello,
2 things:
- The oil level sensor is by nature inaccurate.
- It is now to fail at some point. I had the case on a 120i (N43), where the care would often ask for 1L oil for nothing. I just had to change that sensor and everything was fine afterwards.
