If you check the Sermons of the "Cure of Ars for the Sundays and Feast Days of the Year" published by Jos. Wagner in 1901 (seems not to be available online), you should find (1) in the chapter on Temptations:
The first temptation, my brethren, which the devil prepares for those who have begun to be more zealous in the service of God, is the fear of man. They are afraid to show themselves. They shun those persons whose society they formerly frequented. If they are told that they have changed very much, they are ashamed! The question, βWhat will be said of me?β haunts them so, that they have no more courage to do good before the world. If the devil is unable to win them over through the fear of man, he excites in them extraordinary scruples. They are afraid that their confessions were not good; that their confessor does not understand them; that they are working in vain; that they will be lost anyhow; that they would gain just as much if they did not take any trouble.
and, (2) in the chapter On Perseverance
How often do we not torment ourselves thinking whether we shall be lost or saved? Useless scruples! Listen to Moses, who, when he was dying, had the twelve tribes of Israel assembled, and said to them: "You know that I have loved you tenderly---that I have sought nothing but your happiness and salvation. Now that I am going to give God an account of all my actions, I must tell you the following, and you must not forget it: `Serve God faithfully; remember the many benefits which He has lavished upon you; never separate yourselves from Him, no matter what it may cost you. You will have enemies who will persecute you, and strive all in their power to make you forsake God. Take courage, therefore; you are sure of the Kingdom if you remain faithful to God.'"
I have added the bold in the above excerpts.
There seem to be no other references to scruples in the chapters of the Wagner book.
