Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
Actually, these have level control, but not exactly dynamic range control as the later A6's have.
To do this properly, you need an Audi-specific scan tool to put the headlamp adjuster motors in their base position
do you have this available?
Then the only method you can use is the traditional Beamsetter, or point-on-a-wall method, using the 6mm allen adjusters through the top of the radiator support
Unfortunately on a lot of these older A6's, the side to side adjusters are broken
Is there further information I can help with?
Can you please expand alittle more details on how to adjust on the manual method.
Will this get rid off the Headlight"Symbol" Fault on the Dash?
Thank You Very Much!
