Can someone please tell me how you change the headlamp, (dipped beam) bulb in a Xsara 2.0 HDi (2001) ? The passenger side bulb access point has a cable loom direclty behing it, which makes it impossible to remove. Is there a way to detatch this wiring or is there a knack to removing the cover with the wiring still in place ?

I had a go earlier, but however much I tried I couldn't gain access to the bulb.
