I had to heat my Haldex fill bolt with very low flame after trying lots of different penetrating oils. If you go this route be very careful because there's electronics and wires around the Haldex which can easily melt. I used a makeshift heat shield which helped a little but the wire insulation still softened a bit. But the bolt broke free afterwards!
