This isn't the complete presuppositional argument. Just because a Muslim endorses the transcendental argument and uses it, does not mean he has a right to it. He has no self-authorizing authority upon which to rely. If he appeals to the Koran then he appeals to a book which claims to be an expression of Allah in human language. However the Koran also claims that nothing about Allah can be expressed in human language. The koran is its own worst enemy. And without such a self-authorizing authority he has no foundation upon which to begin a transcendental argument.
If it were that easy, there wouldn't be any Muslims. I'm inclined to agree with you, yet I am sure your objection to the Koran isn't impervious to rebuttal from the followers of Islam.
What is your understanding of the complete presuppositional argument?
Sure there would; self-deception does that to us. Just because you have demonstrated the absurdity of their position does not mean they will give it up. But as far as the apologetics side of the coin goes, you have done your job. You have reduced the fool to foolishness. (Prov 26:4,5) Now the task switches to sharing the gospel. Of course this can take years of constantly reminding the muslim/atheist/JW/mormon/etc. that you have already refuted his position and then sharing the gospel with him at each encounter.
Yes, there are rebuttals to the above argument. I think your referring to the writings of the muslims (forget the name they give to them) in which the contradictions have supposedly been worked out. There are other contradictions besides the one I mentioned. But offering a rebuttal does not disprove the self-contradiction of the koran. The best use of presuppositional apologetics in dealing with muslims was in a radio program Greg Bahnsen did with a muslim and a jewish Rabbi. He also deals with the objections in his series on Practical Apologetics.
As to your question, how detailed do you want it? I think I have a flowchart I put together for a church class.
