I can't remember the exact details you gave, but if it blew up during or after disarm:
If you were an Engineer or Explosives Expert, 1 in 20
If you weren't either of them, 1 in 4.
If you didn't get a disarm option, it might have been similar to the large car IED in the video that is on quite a slope and I needed to search around with the mouse a little to find the disarm option.
Anyway, I couldn't detect any problems in testing today, with 100% success on everything I tried.
Of course I had the advantage of knowing what item was an IED and what not. Another possibility is that you found what you thought was an IED, and when you couldn't disarm it, missed seeing another small IED which subsequently blew up. Dunno, just a thought.
