Could you tell me you if you eventualy found a solution for your problem ?If yes, what was it. @RafalZajac
And for anyone willing to help on my current situation, here is what going on pretty much :
Initial issue:
Ignition coil connector (cyl 4) got burnt, likely from a failing coil zzp highV
Started with intermittent misfire on cylinder 4
Wiggling the wiring near the connector would temporarily fix the misfire
Codes observed:
P0354 (Ignition Coil D Control Circuit)
P0300 previously (random misfire)
StabiliTrak warning appears when misfire is active
Work done so far:
Replaced ignition coil (multiple swaps tested, no change)
Replaced spark plugs
Repaired coil connector:
New connector housing
New pins properly crimped
~15 cm of new 0.75 mm˛ wire added
Verified:
12V supply at coil = OK
Ground = OK
Current situation:
Constant misfire on cylinder 4 (no longer intermittent)
P0354 comes back immediately
No change when wiggling wiring anymore
Engine runs on 3 cylinders (cold worse, slightly better warm but still misfiring)
Im planning to verify continuity of the trigger and feedback wires based on that diagram another user posted, THANK YOU very much for that by the way.
Other then that i ran out of solutions, please help.
Kind regards

Definitely could have destroyed the coil driver in the ECM.
I haven't seen that in a while but it is a thing.
