The coil is not connected to AFM. The power supply 5V is coming from Motronic.
The AFM was not the only place where the short voltage spikes were noticed.
Each time when the engine tried to stall and came back, the DME relay clicked. So, I thought that there might be a problem of power supply to the primary circuit. Attached a digital voltmeter and there were more than 12v in the short moments of stalling.
Sometimes electricity is a mistery.
