This. If youbhave to use the "trust but verify" method then you don't really trust the dealer. If you're that concerned about it, just do it yourself. It's an oil change, not rocket science.
Also, BMW isn't the only company deleting dipsticks. Audi is removing them as well but at least they had the good sense to keep the tube in place, it's just capped off. It's there for service tech to check oil level during services but you can also buy a dipstick and put it in there for your own use.
I wonder if the M has a tube like this.
