Do not fiddle with the OEM adjustment..... only thing which you can attempt is mark the Top screw adjustment and with flips screw driver. rotate clockwise or counter clockwise 3 turns to check whether its going up wards or downwards which is usually needed after LEDs installation. Usually LEDs need 3 turns higher than halogen lamps.
Do not disturb left / right adjustment.
Furthermore there is a you tube video in which it is explained clearly that most of the people choose the Wrong LEDs.... Just go through it and as per @biloo Bilal bhai said, Go for the right one LEDs like the one I and @arkhitekt installed or the one @biloo bhai installed. Rest is Crap as i have extensively searched and found OEM Osram & OEM Philips to be the ones but they are a hell expensive keeping in view the upgrade.
You can put these in Fog lamps & go with the ones we have....
