Young Kidaichi's Murder: File 4 - S2-E4
Factual error: The bittersweet ending is powerful from a dramatic point of view, but also impossible, because law (in Japan, at least) explicitly forbids organs coming from suicide victims to go to their family members, to prevent behaviour exactly like the one displayed here.
Magical Express Murder Case: File 3 - S2-E12
Audio problem: When Kindaichi understands the trick and runs away from the murder room, Miyuki as usual exclaims "Hajime-chan!" but with a curious flub in animation, her tongue moves but not her lips. Try to say "Hajime-chan" keeping your mouth open all the time, it's fun. (00:18:45)
