Flat battery now ABS light won't go off - MOT fail

Hello all,

Apologies as I can see this has been covered before, but I’m still unsure how to proceed and thought I would ask for some help about what I should do next.



I’ve never had any problems with my ABS light before, but unfortunately when I went away on holiday and left the car for a quite a while the battery went flat. Once it was restarted the ABS light came on and now that it is having it’s MOT the garage say they don’t know how to fix it and cannot pass it with the ABS light showing. They say they have run a diagnostics, but cannot find the fault.



I wonder if someone could explain what I should do/ tell my garage to do now?



Thanks,



edit: i have a '97 MGF
