Variations from 0-10 mm are normal. A perfectly flat and level surface does not exist therefore the ECU accepts an error factor called tolerance. To verify the calibration, go to the view current height function in the view value menu. The difference between left and right side current height values should be similar to the difference measured at the wheels.

For example, the measured values from wheel center to the bottom of the wheel arch:

  • Front left = 492 mm
  • Front right = 495 mm

 

And the live values are:

  • Front left = -2 mm
  • Front right = + 3 mm

 

Which brings us to target heights of:

  • Front left 492 + 2 = 494 mm
  • Front Right 495 – 3 = 492 mm

The difference being 2 mm, this confirms a good calibration of the front sensors.
