Help with dating components

[box]

Below are pictures of 3 coil packs. 2 were replaced at the same time and one was replaced substantially earlier. Is it possible to tell which is which from the images and information on top of the coil packs? I have by own ideas, but would appreciate some other opinions.

Coil Pack 1

036 905 715 E
EDT S3
ELDOR 78292004
Turkey e13 02XXXX
006F5 111 3 39/08 0


Coil Pack 2

VW AG
036 905 715
EE1 S3
ELDOR 78180008

Coil Pack 3

did anyone else see the thread title and think "he wants to know what's used and where it oes in dating...." lol

Hehe, I was a bit hesitant about posting that title, but it did get people reading the thread!

The end letter on the top row of numbers is the coil pack revision (or thats how it works for my pencil coils anyways).

This makes sense, and seems to agree with the 'week/year number' figures.

Thanks for the help guys
