You do not have to sign an audit. We never agree to sign extensions. Why? Because that will give the auditor additional time to beef up the file and, if it is obvious that the matter is going to go disagreed at audit, you don't want to give the auditor any more of your (i) facts or to (ii) arguments. You would prefer to keep both for use at the Appeals division. If you have no new facts and no new arguments, then it makes it difficult for the Appeals officer to rule in your favor.
