You CAN adjust the dipped and main beam independently in each head lamp unit. My Left side main beam was too high, I found that the dipped assembly is mounted on four green rubber spacer washers. The lower washer were very loose, I tightened these which squashed them in, this brought the dipped beam up to the height on the main. I then lowered the whole head lamp via the 6mm adjuster. Now left and right (dipped/main) match perfectly.
