The problem is you then learn to ignore the ding when there is a real issue at hand. Like a low fuel warning. Don't ask...

Oh my car gets absolutely obnoxious when it thinks it is below 35 miles to empty. Warning in normal gauge cluster and warnings at bottom of iDrive screen and BINGS all over.

I wanted to share my experience with resetting the E90 oil service reminder. When I first bought my car it had 218K miles (yes, call me crazy for buying a high mileage BMW but the price was right) and I immediately did an oil change. The reminder reset and showed 4300 miles until the next oil change. At around 222k miles I changed the oil again and I wasn't able to reset it. I tried several methods, using the BC stick on the left side of the steering wheel acted like it reset but after the clock symbol the remaining mileage didn't change. I tried tool32 on my laptop and while I confirmed it incremented the oil service reset count, it never actually cleared anything.

I was reluctant to take my car into a dealership to have the oil service programmed out so I used the instructions in the PDF attached to the first post in this thread along with ISTA+ software to remove the oil service indicator myself. I spent more time waiting for my laptop to boot than it took to perform the coding. It's literally just navigating a few menus and takes a few seconds to execute the job. NO MORE OVERDUE OIL CHANGE REMINDER! It was also removed from the iDrive display - previously the first row had the oil change but that's gone now.

I think this is happening to my car as well now. 2006 E90 330i. I had the last oil service done at BMW at about 222k miles. Right now it has about 224k miles and the oil service will only reset to zero but counts backwards, or negative. I just found this thread and just ordered a scan tool but i was hoping to:
1. read the code with a scan tool, possible deactivate it if supported
2. Talk to (waiting for a call back) from my local BMW about the bulletin and see if they will deactivate it free, showing the bulletin
3. pursue DIY deactivate with some type of software.

I still have to look at this post in full, but it looks like there isn't another problem elsewhere, like I originally thought, with a level sensor or pressure sensor. Also the last two posts had members with similar mileage as mine, which i found strange and nowhere near 300,000 kilometers

So the deactivation is programmed to trigger at 300,000 kilometers (186,000 miles). The OCI interval is dictated by more than just the oil quality data from the oil sensor in the oil pan, so the ECU calculates the next OCI based on the last oil quality data it gets. If you use an "assumed" 15,000-mile typical OCI the next oil change after 186,000 miles 200,000 is where the system starts to stop calculating. I changed the oil in my car at 195K and at 212K is when my reset started showing the problem. At 221K, the CBS wouldn't reset and does what yours is doing now.

Just get the software patch coded, that is the only thing your car needs.

Okay tool32 or insta? Which is more user friendly if I have neither ? Thanks for following up, you’ve been great at being on it. Glad it doesn’t need a real repair at least.

I don't know. I had a dealership do mine. Look over on the Coding subforum. Several guys over there figured it out a few years back.

Even with the engine oil quality or life no longer working, when you get the check engine level "Inactive" signal.....does it still read the oil level correctly?

The oil level function is independent of the condition-based oil change interval deactivation. When you follow the steps in the first post of the thread (pdf attachment) and deactivate the CBS, that just deactivates/removes the oil change interval and reminder from the car. The oil level sensor still reports the oil level of the car, and still gives you the notification to add oil when it's low.

If you're getting "Inactive" on the oil level menu, there's a problem with something on the BSD bus. That isn't related to the oil change interval. I actually had this happen to me - started seeing "Inactive" when checking the oil level (long after I disabled the CBS oil change interval). I initially thought I had a bad oil level sensor, however when I scanned the codes using ISTA+ it provided the diagnostics procedure which required disconnecting the devices on the BSD bus one by one until the bus was functional again, with ISTA+ monitoring the status in real-time. Water pump, alternator, oil level sensor, and intelligent battery sensor (IBS) are the four things connected to the Bit Serial Device (BSD) bus. In my case once I disconnected the water pump the bus was functional again, and replacing the water pump fixed the problem.

FWIW, this glitch seems to slowly fade..

At 242K, my oil Life warning alert no longer appears all the time. Sometimes system check reads “ok”, with no red triangle. Occas I can even reset oil life monitor (to 22K, for example), but it doesn’t last for more than a few miles. Yes, it’s a software glitch, an inconsistent one at that.

Original oil level sensor is still working fine..

[razzy530]

It is set at maximum 25 lifetime resets. At which point you can no longer reset the intervals and have to code it out. I’m about to do this soon on my e60 at 221,000 miles

We've been through this discussion point. hassmaschine found nowhere in the code that has a max reset limit. My car developed the reset issue at oil change #14.

[cliffschum]

Dealer disabled oil monitor for free, when vehicle was in for PCV heater recall several months ago..

CBS works fine now, 246K miles..

Yes, you read that correctly. On the E90 (at least for my 2006 325i) the CBS oil service indicator (oil life monitor) is programmed to stop working after 300,000 kilometers (186,000 miles). The system is programmed to stop processing the oil quality data provided by the oil quality/oil level sensor that is in the oil pan. If you are not familiar with the CBS oil life monitor system, the sensor that determines the level of the oil in the engine also measures the quality of the oil though a practice of measuring the dielectric of the oil. I’ve discussed this system several times on several different threads and it is one of the reasons long oil change intervals are achievable with BMWs. The oil quality sensor provides oil quality data to the CBS that is used as part of the data input to the BMW algorithm used to determine when the oil needs changing.

Attached is the service notification to the dealer that BMW publishes when a customer comes in with a complaint that the oil service indicator will not reset, or resets to a lower value than normal. In my case, according to BMW North America, I am the first owner to experience this issue. When I changed my oil at 212,000 miles, the CBS would not reset to the normal oil change interval (OCI) of about 18,000 and only reset to 9,700 miles. At 221,000 miles the CBS notified that an oil change was due (a 9,100 mile OCI vs. the usual 17,500 miles I normally have) and the CBS would only reset to 0 (zero) miles.

The problem is now every time I start the car it dings and indicates the oil service is past due. If you read the attached document, it explains the procedure for the dealer to follow to code out the oil service notification and instructs the dealer to tell the customer to change the oil on a predetermined interval of 7,500 miles. Based on my driving style and conditions, my OCI would average about 17,500 miles based on the CBS system.

Once I discovered that the CBS would not reset past 0 miles, I concluded the oil level sensor was bad. I thought that if the CBS wasn’t getting oil quality data from the sensor, it wouldn’t let the system reset. Also I had noticed the CBS oil monitor function had been behaving differently in the past year with not being able to reset using my BT scan tool (but it still would reset with the turn signal stalk). Additionally, after an oil change the system would immediately indicate, after proper engine warm up, a full 7 quarts of oil in the engine; with the 212K and 221K oil services, the system would not immediately recognize the full complement of oil until about double the time and drive cycle necessary to warm up the engine; it would only report the last oil level before the change; meaning if the engine was a ½ quart low before the change, it reported a ½ quart after the change, which I know was not correct because I always refill with 7 quarts. And further, the presumed oil consumption of my engine, based on the drop in oil level as measured by the e-dipstick, had drastically changed from around 13,000 miles per quart of oil, down to about 6,500 miles. My engine is still in great shape (the average MPG has dropped off only about 0.6 MPG since the car was new) and has a light-weeping oil pan gasket leak.

So I changed out the oil level sensor (as a DIY). The part is around $160. The new sensor did not change the behavior of the system and the CBS still would not reset. So, figuring it was a software issue, off to BMW of Sterling I went. BMW of Sterling, who was great in really trying to solve the issue BTW, had my car for 8 days. BMW of Sterling followed the procedure noted in the attached bulletin, and when that didn’t work, they hooked my car up to the BMW NA engineering network to let BMW’s NA engineering department have a crack at it. BMW NA couldn’t fix it either, and opened a PUMA case, sending the issue off to BMW AG.

And that’s the problem. It’s been four (4) months since all this took place, and BMW has not addressed the issue. I spoke with Sterling’s customer advisor today, and he said it is not a priority for BMW to solve the issue. So I suggested that when buying my next car (keep in mind my E90 has 236,000 miles on it) purchasing a BMW will not be my priority after 25 years and 650,000 combined miles of BMW ownership. I should add that BMW of Sterling initially agreed to charging me a $160 diagnosis fee to chase the issue down, but after it came apparent that the problem was a software issue purposely engineered by BMW AG, Sterling kindly did not charge me anything (I suggested that I shouldn't have to pay for it since the car actually didn't break - they agreed), and I had their loaner car for a week at no charge.

I’ve been quite patient with this waiting for BMW to address it. I tried to get to BMW NA directly to take the matter up with them by calling the BMW Customer Service hot line. That process was a complete joke. After 30 minutes of heated discussion (just asking for a point of contact at BMW NA), I was switched to a “Customer Resolution Specialist”, who when I asked for a BMW NA phone number said “Okay, 1-800-….” he started reading me the customer service number I was calling on! (Needless to say that really pissed me off). All the BMW Customer Service line is a call center in Columbus, Ohio; they will tell you that they are not affiliated with BMW NA (WTF?). They refused to give me a POC at BMW NA in New Jersey. All they can do for you is either call the dealer (my issue isn't with the dealer), or "register a complaint with no expectation of resolution", so my advice is don't bother calling the BMW Customer center because it is a complete waste of time. I’ve been clear with everyone at BMW of Sterling that this whole thing about the E90 software being pre-programmed to stop processing the oil life monitor data at 186,000 miles is totally stupid, and that I’m highly disappointed at the customer service I’ve received from BMW North America and BMW AG. I wasn’t discouraged from posting the issue to the BMW community…

So, it’s posted…

Update on Last Page

WOWIE -
it is indeed shameful that you were placed in the spin cycle with no apparent off-switch to get out....i too would be if the customer service "professional" on the phone call provided me with the SAME PHONE NUMBER that i had just called.

why would BMW intentionally design a process to eliminate OCI @ 300K K's? did they think no one would achieve high(er) mileage?

Does anyone know if Carly can be used to program this feature?

Curious if anyone else is seeing this based on number of oil changes or even overall time? Our 2011 328i won't reset anymore. It only has 93K on it, but since around 2016 it's been getting less than 5K a year and I've been changing it yearly. I've changed it 9 times starting at 56K. I'd have to check the records from when the car was still under the BMW service, but I don't think there were more than 3 that BMW did so I'd say it's been 12 changes max.

My car is getting up there in miles, and I am thinking about the time when I will need to code out the oil life monitor. The instructions in the first post seem simple enough, but are those for INPA, ISTA, or either one?
