Could it be that the first time through it found the newest--and you didn't keep
track of that first filename?

Option Explicit

Sub Auto_Open()

Dim Dat As Date
Dim DatVgl As Date
Dim Mappe As String
Dim ZMappe As String '<-- added

Const s = _
"c:\temp"
Mappe = Dir(s & "\*.xls")
Dat = FileDateTime(s & "\" & Mappe)

ZMappe = s & "\" & Mappe '<-- added

Do Until Mappe = ""
DatVgl = FileDateTime(s & "\" & Mappe)
If DatVgl Dat Then
Dat = DatVgl
ZMappe = s & "\" & Mappe
End If
Mappe = Dir()
Loop

Workbooks.Open Filename:=ZMappe

End Sub
