  Ignition coils, location   GF15.10-P-3102-01G 
  Ignition coils, task Providing adequate ignition energy for the respective ignition circuit in all operating conditions  
  Ignition coils, design Engines 104, 111 
The twin spark ignition coils (T1/1, T1/2, T1/3) are mounted directly onto a spark plug together with a spark plug connector via the secondary output (4a). The secondary output (4b) leads via an ignition cable to the other cylinder. The guide sleeve (W) is at the same time the ground connection for the ignition coil. The voltage is supplied fuse-protected by the ignition/starter switch
Engine 166 
Two twin spark ignition coils are used, which are combined in a housing, the ignition coil module (T2)
