190E M103 eating ignition coils

Hello,

I made a post a couple of weeks ago about my car having twitchy tachometer and the problem turned out to be my ignition coil.

M103/190E Twitching Idle and Error Code 29

I replaced it with a good spare (but used) ignition coil and after about 2 weeks of good use, I am having the same exact problems again.

I have a feeling something is destroying my ignition coil. how should I diagnose this?
