Oh great...that's how I lost my lost engine. Cam's seized and that screwed up the top end. Didn't feel like fixing it. Well I'll have to hope that computer keeps on working!
 
Thanks for the feedback.

..there is another way.
 
The dealerships drain the oil, measure the results, figure an extra liter (or there abouts) of oil is in the oil filter, and you have your results.

But if I drain it, then I can only tell if I was short. Trying to fgure a way to tell if I'm short w/o relying on the computer. bummer..

Yessir, you are exactly correct. It's bad enough to have no dipstick, but when the substitute proves to be unreliable and very expensive to repair. . .
 
That, plus the run-flat tires, explain why the car I lusted for over the past four years isn't in my garage at the moment.
 
Now, to add to the joy, the prices are up and the residuals are down.
 
Gotta love them BMWs.

Thanks for the response(s)... given that I had left my car with the mechanic for two days (very inconvenient for me professionally). I went ahead and had him replace the oil separator (no offense, Shipo). Not sure if it will help, but I'll keep monitoring it.
 
js330xi-- thanks for the info... on one level, this is good to know; and on another level, this is bothersome that it's just something to "live with". But, sounds like your car is still driving and operating fine, despite the consumption.
 
Seriously... this means that by the time you get to the regular oil change (7500 interval), then you are in fact draining out relatively new oil (ie, the oil put in at the previous oil change is already gone and replaced by these 7 "top-ups"). Bummer.

Uhhh, what was I supposed to possibly take offense at? Personally I think the oil separator and/or anything else to do with the PCV system is a very good place to start when there is unexplained oil consumption, regardless of what type of engine or who built it.

Sorry... I meant to apologize to Mr Shiftright, who asked "what if he's $300 wrong?".

Oh a mere rhetorical question, that's all I was posing....I was wondering what he'd say if it didn't work. But I hope it does for your sake

I'm unclear on how a "liter (or there abouts) of oil" can be left in the filter. I have 2007 328xi. I am having the dealer change the oil for "free" during initial maintenance program at the 15K+ (aprox) intervals as called for by the car's computer. I change the oil myself at the intervening 7500K interval. First the oil is drained from under the car via the bolt opening in the pan. Then the filter housing cap is removed. At this point there is perhaps 30ML of oil remaining in the housing. As I assume you know BMW oil filters for this engine are not constructed in a self contained cartridge as is typical of most other manufactures. They are simple filters and when removed are only moist with oil holding I would guess no more than 20ML of oil. I look forward to your reply.

Hmmm, that's odd, when I screwed off the caps of the filter canisters on my BMWs, I always found them to be basically full. After pulling the filter element out (which holds a fair amount of oil in-and-of-itself) I always had to extract considerably over a half of a liter of used oil before the canister was completely empty. That yours was basically empty has me at a loss.
