If the E70 headlights work like the E53's, there maybe a misconception about the "auto-leveling" feature in X5 head lights. On an E53 they don't actually level themselves in an absolute sense. They adjust themselves within a fairly narrow range to compensate for the suspension not being level. IOW their "auto-leveling" adjustments are relative to an initial manually adjusted setting. Which on an E53 is extremely simple to change with the two large plastic knobs on the back of each head light housing.

In a previous life.... I foolishly believed that an authorized BMW dealer would properly install/adjust my E53's headlights after replacing one of the bulbs - WRONG. On coming traffic immediate started 'flashing' me even when I was already on dims. So I drove the X5 up to a flat wall and realized that the headlight BMW had 'repaired' was set to blind oncoming traffic. It was way too high and a little to the left. I adjusted it down and in. Then checked it by driving toward it in the ranch truck on various nearby roads.
