my s4 (98) headlights are aimed too low. am i right in thinking these have auto leveling on them. should i adjust them using the manual adjust or could it be the case that the auto leveling is not working. how can i tell if they are working. note their is no codes up when vag-com was pluged in. i had a thought the other day that the headlights were removed when the timing belt was done and the auto leveling not been reset. could this be the case? basicaly i dont want to go adjusting them to find out the auto leveling (if there is one) is just not working/needing reset. thanks in advance.
