hmm, cant find it..anyway..
its actually an ignition coil.
Basically, modern cars dont have distributors and spark plugs anymore.
They utilise a computer controlled system employing a coil pack to distribute charge to ignition coils.
For every cylinder you have, there is an ignition coil which goes into the cylinder and supplies it with the precise amount of sparkage it needs.
The advantage of this system is that the onbboard computer can control the running charateristics based on various inputs down to the thousanth of a second and use the precise amount of charge needed for the job at hand.
Now bosch apparantly supplied some faulty ignition coils back in 2001, and these are going in several cars now.
What happens is that one of the ignition coils goes, and the car runs on one less cylinder than its supposed to, it runs very roughly, and has significantly reduced power.
Dont run it for too long in this state, stop as soon as its safe to do so as unburnt fuel may enter the catalytic convertor... and also several other things could occur.

well, they replaced all 4 on ours without asking. Its a modified ignition coil so should be fine.
but in america, it seems they have a policy to only replace the faulty coil... maybe I was just lucky and they replaced all 4 without even asking on ours.

official documents pertaining to what?..
dont have any official ones..soz..
In relation to them replacing all 4, everyone ive seen on this board from the US whos had the problem had the dealer only replace the faulty one... with them replaceing all the others if another goes.
This may be to do with an ignition coil shortage in the US rather than anything else.
