There have been no changes to the 328d in the US. Everybody over here has the same engine. 5.5quarts is just about 5.2L anyways, not sure why you decided to switch unit of measures without doing the conversion?

Also, there isn't a set mileage to change the oil. The ECU in the car decides when it's time to change based on how the car was driven. Not sure exactly how it calculates it, but when you get down to below a couple thousand miles left before an oil change, you'll see it move around depending on your driving style.

I didn't realize you said quarts. My bad.

Also the oil is set on a specific mileage and time, unlike your brakes. Your brakes also have recommended mileage and time frame but if the brake wear sensor detects the pad is to worn, it'll shorten the time frame appropriately.

The oil service interval is set on a schedule based on your specific vehicle. The interval is coded into your FA and it does not fluctuate based on drive style. All the computer measures is if you are at the right amount of fluid or if you are low on fluid.

"It is unclear whether the CBS system takes into account these factors, so it is important to be aware of this and to check your oil periodically, especially for older vehicles with higher mileage."

Like I said before. There are only sensors that measure the oils levels to make sure it's not to full or to low, Incase there's leak that you don't know about and are risking running your engine on low oil. The CBS is set only to to keep track of service intervals. The brakes are the only part on CBS that actually has a sensor to measure the pads so the hard you brake the faster they rundown and the cbs will adjust he brake interval accordingly.

Your comments intrigued me and just to make sure I did some research on ISTA+ and that confirmed my information.

Some other models or maybe newer cars with updated clusters and iDrive version, may in fact have these capabilities but I have not researched nor experienced that for myself and I have not heard anything from anyone else.

In the end, it is maybe recommended to shorten your oil interval if you drive hard and beat on the car, but the CBS or iDrive will not measure those factors. If you drive like that, frequently check your oil manually from the dip stick and check the condition of the oil... as advised in the article you linked above.

Sorry man, you're flat wrong. I was near the 1000 mile mark before my oil service was due. I took a long trip (700 miles) and when I got back my oil needed to be changed in... ... 1000 miles. It takes into account driving style and conditions. Just like as noted in the article:

Quote:
The CBS system tracks oil life through mileage, the amount of fuel consumption, and information about oil quality from a sensor located in the oil pan.
The line you cherry picked (without including the very pertinent previous line!!!) refers to ambient temperatures and driving terriain:
Quote:
Certain driving habits can affect the life of the oil, as well as driving conditions such as temperature and driving terrain. Lighter, more moderate driving conditions and temperature will require less frequent oil changes and maintenance, while more severe driving conditions will require more frequent oil changes and maintenance. It is unclear whether the CBS system takes into account these factors...
Since you did so much research:

Why don't you include that research instead of just stating that you confirmed your information?

The reset h just brought back, that there are no sensors that read and measure those factors. Really take a look at your article.... even it tells you, it's unclear if the CBS takes the factors into account. It's pure speculation and with no findings of sensors or any information on ISTA that says anything about these measurements... there not much to say. If you want to believe you have a special car that has this extensive technology, that's up to you... but on mine and all others do not, to my knowledge. Until you can find a bmw part# and description of the sensors that actually measure those factors, I'm done arguing with you. It's a waste of my time. Have a good day.

I agree there's no sensor in the pan for measuring impurities. However, no extra sensors are required to measure fuel consumption, RPM, vehicle speed, and engine temperature. Having seen it myself, I know my car adjusts it's oil change interval based on how the car is being driven.

And again, you need to brush up on reading comprehension. The factors they're talking about in that particular sentence are ambient temperature and driving terrain.

Well like I said, maybe you have a special cbs and one of a kind model... or maybe your cbs is just acting up. You might want to contact a dealer and have it looked at.

Please check out the fourth paragraph in the attached PDF of this thread regarding CBS intervals:


Quote:
BMW vehicles' CBS computes the actual optimum maintenance requirements based not only upon the accumulated mileage, but also taking into account important factors pertaining to fuel consumption such as high or low engine speeds, short or long-trip driving. Such computations can result in variations from the 10,000 mile interval and correspondingly, when an engine oil service will actually display "Recommended" or "Due."
So.... you were saying??
