[formerE36M3/4/5]

I'm a long time Porsche owner and have done much of the maintenance myself (I use a QuickJack lift) and I plan to do a good bit of the maintenance on my recently ordered G05 i40 (I know BMW covers most of the maintenance for the first 3 years).

- Is the oil change interval at 10k miles (as with Porsche) or is it determined by an on board system? If it's not 10K at what mileage does the system call for an oil change?
- Can you reset the oil service system via on-board tools or do you need a separate tool?
- I believe the BMW I-6 engine is fairly robust and reliable engine, does it have an issue with oil leaks? (the Porsche V6's have a problem with them and that's one of my pet peeves, a $90k+ car should not have an issue with oil leaks!).

Thanks for indulging me....
