In US, we don't have it, but the other day I was trying to adjust them with my screwdriver and was amazed how they won't budge. I sprayed some of WD-40... liquid wrench... lubricants that help loosed rusted or siezed bolts. I worked the screws in and out unttil it was easy to adjust the headlight and it worked wonder.
I suspect you have the problem that the screws won't budge and the motors are screaming... trying to turn those siezed screws. So try using lubricants to loosen and maybe perhap anti-seize compound for permenant fix.
