 Thank you!

agree  muttersprachler: Ich halte das auf Deutsch für schlecht formuliert. "harmonische 12. Ordnung der M." oder kurz "12. Harmonische der M." wäre besser gewesen.

Explanation:
Motordrehzahl is engine speed, rpm (Langenscheidt Technik).

I'm not an automotive specialist, but I found this explanation that might help.
---
After your road test, park the vehicle and bring the engine speed up to the same speed that it was vibrating at on the road test. If the vibration is present, record the Vibration RPM and Engine RPM on the vibration worksheet. Mark the point on the vibration worksheet where your Vibration RPM and your Engine RPM readings intersect. The point of intersection should be on or near a vibration line on the vibration worksheet. Each line is identified with an abbreviation like E1. E1 represents a first order engine speed related vibration.
Order The number of disturbances or shakes in one revolution of a rotating component.
