Well, if you look at it this way. The first one was the original and went bad (they all go at some point and time). You installed a brand new at the time, 3 years ago? The next one was also a brand new I assume and you installed it 1 year ago?
If you installed used ones all bets are off.
It is no complete guarantee that a brand new will not have an inside defect that might shorten it's life.
And it might not even be the ignition cassette this time. You won't know until installing a new one and all the symptoms goes away or if the symptoms stay you know it is something else.
It might be a slight chance that the Trionic computer drops the ground signal to fuel pump/injection relays for a split second creating a hiccup, and that is the relay click you hear.
I had that happening on a 93 9000 ones and it took me a long time before I narrowed it down and realized that the Trionic ECU was bad.
It wasn't until I hooked up a sensitive node testlight to the trigger ground wire for those relays that I found the problem. A regular test light didn't do the trick since the split second glitch was to fast for the test light bulb to react.
Now with a high speed labscope in my possesion it would be easier to see the glitch when it happens.
