HID auto-leveling problems?
Since the headlamp replacement cured the problem (albeit expensively for Audi) I'm putting it down to an intermittent 'open' on one of the connector leads -- hope springs eternal -- or gremlins within the lamp's motor electronics. A search on the UK-based Audi board last year showed that many A3s under warranty had the motors replaced rather than the headlamp assemblies, so that may help narrow it down.
Let us know if you find out anything that pins this problem down -- a number of others have posted here about it but I haven't seen a diagnosis.
