Solve on F-Puzzles (Note: It won't check the extra constraint)
Rules: Normal Sudoku rules apply. The digit in any purple cell is equal to the sum of exactly two of its orthogonal neighbours, exactly one way.
eg: A purple 7 would be satisfied with 3 and 4 as neighbours, but its other neighbours could then not be a 2-5 pair, nor a 1-6 pair, nor could they contain another 3 or 4.
Example
Thanks to Stefan and gtkrouwel for testing.
Good luck and happy solving!
Solution code: Row 9, then column 8. 18 digits, no spaces.

Regel nicht klar: darf auch eine purple Zelle zur Summe einer benachbarten purple Zelle beitragen?
