The cause of your car being lower is the suspension settling...This is why they want you to wait for the alignment 500kms. Aligning the car before the suspension settles is a waste of time...unless the spring swap changes the toe angle to a significant enough degree to destroy tires really fast. Toe angle will destroy tires faster than any other angle. Best Practice is to do a quick "toe set" when you do the springs to make sure the toe isn't wacky off. Then bring the car back after a few weeks to do a proper alignment.
Alignments do NOT alter the ride heigh in 99% of passenger vehicles. (your 3 series is in this 99%)
Note - I used to do that for a living to put myself through college.
