Forester automatic headlamp levelling.

[MackL98]

Hi..

I have a 2008 Forester with the auto HID headlamp levelling system. 

The lamps seem to shine a bit low and occasionally, I get the orange warning lamp appear but not for long.

Ive visually inspected the the front and rear suspension sensors, and they appear ok. Ive disconnected the module itself which made no difference and I've carried out the calibration procedure which also had no effect (no 3 flashes etc).

My question is:

As the dipped and main beam lamps are separate, which of them are levelled automatically, one of them or both.. The calibration procedure refers to the "headlamps", so is that the dipped or main beam?

Does the whole headlamp unit move during the levelling action or just one specific lamp, dipped or main?
