NOTE-
Ignition coils and power output stages are a combined
unit.
Ignition coil primary and secondary resistance cannot
be measured.

Ignition coils can be very sensitive to moisture which
can cause mis-firing. If replacing, always check with
and Authorized Volkswagen dealer or other knowledgeable
parts Professional to be sure of obtaining
the latest version.
If no faults are found with the supply voltage, impulse signal
or wiring, then the faulty ignition coils should be replaced.

yeah alot of people have even cracked them open and tried to see what actually fails in them. its kinda a mystery. they are cheap enough to just buy 4 new ones and keep the old ones as backups. i keep 3 in my cubby in the hatch.
