About to place a lease order - advice please

Not true - they are adjusted the same way as any light, using a hex driver in the white adjusters on the light.

The car only needs to be plugged in and put into learn mode for the upper and lower tolerances on the self levelling system, and to program the AFS.

Which is what i said.

If you do not plug in VCDS / ODID / VAS whilst adjusting them you stand a real chance of the lights coming off the adjusters (and potentially snapping the adjusters) when they do their start up self check.

Yes, but it needs to be hooked up to VCDS or the dealers tool whilst being adjusted.
