I would need a lot more information in order to answer this question. Have you spoken with your probation officer about what they want to do to you? Have you ever been brought to the courts before for not complying with probation? Is this your first offense of DUI/DWAI?
You should at least call an attorney for a consultation on your issue - if not just hire one to represent you at the hearing.
