Weird Oil Life reset issue. 2008 535xi

I changed oil and filter 2 months/2000 miles ago. A few weeks after the Service Due light came on for oil change. I figured I forgot to reset it and so I reset it with the Foxwell tool. The next day it cam back. I've reset it a few more times and then used Carly for a reset, every time the warning returns almost as soon as I start the car.
I finally looked up the dash reset using the trip odometer button. It reported a successful reset to 15,000 miles. The next startup gave me the Service Due warning again.
It's always engine oil. Everything else seems fine.
Any ideas?

The car does have a CBS (condition based service) element to oil changes. Perhaps whatever triggers a oil change event that is not mileage based is malfunctioning and the system is just responding to that. I don't know what all goes into the car deciding anything other than mileage for an oil change.

I thought it checked oil condition as well as miles. I may have to drain the oil and check if it is contaminated. I pulled the filter out this morning and the oil looked and smelled normal. I do have a fuel mixture problem that I think is injector related. Guess I should look into that, too.

Thanks!

I've read that the oil level sensor has condition sensing electrodes to measure oil conductivity or such. I shall research more. Car seems to read oil level fine, maybe a little slow to appear...

The sensor for oil level, condition, and temperature is all 1 unit.

Thanks for this info.
I doubt the sensor is the issue as I have no codes. I will drain the oil and see what it looks like. If it is contaminated, I'd think there would be something visible. I may just change it and the filter anyway.

Today it shows one green square down from full which matches the normal consumption for this car.

It's a weird situation.

The type of oil matters as well. The additive package in the synthetic oil affects how the sensor works, which is by measuring the dielectric constant of the oil. In other words, it's a capacitor based measuring system. The wrong oil gives a funky measurement value.

I've used Mobil 1 Euro 0w-40 since we bought the car in 2014. I used Castrol Edge Euro a couple of times because I found a great deal on it but went back to Mobil 1 as it is easy to find. LL-01 oils are kinda rare. I know, Mobil 1 isn't LL-01 any more but the standard changed, not the oil.

Thanks for the info tho... every little bit helps.

Have you used any additives?

I tried Certek (molybdenum) from Liquimoly. Worked well for what it does, but after several months I noticed my CBS data was rapidly reducing my remaining miles much faster than normal, down to few hundred remaining miles when I started the car.

Replaced the oil, and over the next month the sensor returned to a normal reading. I assume the Certek was interfering with the readings.

That's good to know.
I think I'll change oil and filter today.
No additives in it tho...
