New here and need some help f30

Howzit gents been browsing the forum for a while now after recently picking up my 320i f30 m sport , lovely cars they are coming from a Golf R its a lot slower but its also alot more refined . Anyway , i picked the car up used and noticed that the low beams are way way too low , have to basically drive them on high beam all the time and get flashed by oncoming traffic like mad . Is there anyone that can give some advice and or help me out with adjusting them to the right level ? car is still on plan but the stealer wants me to book the cab in for a day and time is somehing i dont have right now .
