Checked the bulbs ? Bi-Xenons are dual-beam bulbs (one bulb for both the low and high beam function) .

Came across this , don't know if relevant to your car or not , not really familiar with the lighting set up on VX Insignias

" Are these AFL type lights ? If you turn your steering wheel do your lights move as should ? If not it's a possibility your AFL sensor needs replacing. It's a gadget on the steering system when it fails it affects your lights .

It does stop the headlight bulb main beam working . The sensor will need testing to prove wether it just needs recalibration or replacement. Will certainly need a garage that knows what their doing.

I know it stops the main beam from working . I've heard stories of AFL equipped Insignia needing a new headlamp unit which can cost around £890 . "
