I would like to ask if the height adjusters (front/back)  from Xenon range can be able to report any fault code in case of mulfunction/broken part  themselves?

Last days/weeks  i think when heavier load in back, the right projector's beam aims i think somehow a lot higher..
I have not made any adjustments in the lightning modules,  just changed the shocks in all wheels but this was a year back.

Do those levers fail anytime  and possibly affected from other reasons?

additionally , if i adjust manually a bit the projectors from the screws, without VCDS range controller , will it have any problem or need to pass command to learn new position?
