I actually lost very little oil, yours is likely the same. It just sucked to have the oil film all over everything, as well as the drips on my floor. I wouldn't worry enough to flatbed it - you can still accurately check the oil level on iDrive or the dash. To be honest, my biggest complaint was the complete incompetence of he tech in replacing the cap. You can see from the pix how obvious the problem is. Now if only BMW would design a cap that's as effective as the cap on my 69 cent bottle of diet coke!
