ABS Module removal

[RugbyXV]

HI,

I've been away for a couple of months and now my A8 has developed a myriad of problems.....ABS module, EPB faults and level sensor issues. I want to get the ABS module done first as it dumps the speedo' and power steering when
the lights come on which is quite regular now.

I need to get my ABS module repaired and getting it off is proving a bit of a problem. Has anyone encountered the torx screw heads being rounded and if so, how did you get them out?

Any help gratefully received as always...
