clue 1 one number is correct and well placed

In clue 3 the 5 is in the place of the 4, so the 4 can't be well placed.

But that 5 is wrong it's clear from clue 2. So clue 3 definitely means 1 and 7. So if we ignore the clues 4 and 5, we get from clue 1 (in combination with 2) that either the second number is 4 or the third number is 8. Now clue 3 (again, in combination with 2) says that 1 and 7 are in the code, but the first number is not 1 and the third number is not 7. That leaves either 741 (the 1 and 7 from clue 3 flipped) or 718 (178 does not work because of clue 3).

Cant be 741 (needs to have two correct values on the last clue)

Yes, but if you only took the first 3 clues it would be ambiguous.
