Faulty Oil Level Reading ?

[Clubber]

Hey everyone,

Couple of months ago I started seeing drops in digital oil level on my cesil. Instant readout (hold the sport button ) shows it full almost all the time but the digital average keeps dropping .1 in every 3-400 kms.

To be on the safe side, I installed E46 M3 oil stick for actual level check and the car always shows full on the stick. I replaced the oil lever sensor (12617508003) but still the same. Dropping constantly on average readout. I know the cars has adequate oil at all times but hate seeing the digital reading dropping like a fuel gauge as I am on a long drive.

Any suggestions ?

So every few hundred KM it goes down by 0.1, but then when you park the car, does the reading come back up to what you'd expect?

Exactly. When I park and do instant measurement with holding sport button, it shows 1.0 -1.1. But the average reading keeps falling. Untill i get a yellow oil light at 0.1 average
Funny thing is if I fill more oil, even though it is physcially full, the average level goes back up.

For some reason the digital system requires more oil even when the car doesn't mechanically.

Any ideas people ?

It can take a while for the digital gauge to become accurate.

Short journeys are the worst, then it changes on a long journey, then if you top up the same thing happens again. You might not of gave it time to settle.

I know the adaptation time. What I mention is AFTER that. It starts dropping and keeps dropping until yellow oil light is on but when checked manually, the oil is full.
