A coil pack is group of ignition coils and it works by utilising a sensor on the crankshaft that tells the computer when it needs to fire which coil. On the later Volkswagen models such as the MKV coil packs replaced the distributor. Each coil operates one-fourth as often as do coils on engines with distributors, which extends the life of each coil. It eliminates lots moving parts which means there is less to break and it also allows for a stronger spark to every spark plug since the spark doesn't have to arc and jump from stator to cap.

Pop the bonnet by pulling the bonnet release on the driver's side near the hinge of the door.
Disconnect the battery by unbolting the ground lead and removing it from the battery. Secure it back to prevent any contact with the battery.
Remove the engine cover using an Allen wrench to expose the coil pack.
Locate the coil pack on the engine. It is a small black box; each of the spark plug wires leads into one.
Disconnect the wiring harness from the coil pack by pressing in the small tab and pulling it straight off.
Use needle-nose pliers to pry the coil pack off the spark plugs and out of the engine.
