Hi Rachel, I found a list of codes below. Code 30 is for licences issued before 28th November 2016 and is a combined code for braking and accelerator systems, which I would say code 32 is the most applicable. But you do not mention adaptions to the braking system and only the accelerator in which case code 25 is the most applicable. Hope this helps a little, sorry can’t help anymore.
