if possible what i would love to see are pictures of how each coil is tested with the multi meter for resistance. also your last picture showed a coil split open. is the spring mechanically attached to the coil, or is it just pushed down? reason i ask is i have a used coil pack that had a couple of springs missing. i was able to find springs locally that fit over the interior piece in the coil pack and seem to be securely attached. will this work, or is there some type of internal connection?
thanks

the measuring is next to be published, at least a easy way
about the spring, it is just pushed in, nothing else
problem is, it is wider in the middle, so difficult to grab the lower part
if you pull on the higher end it will come out but your spring will be dead
so I suggest bending a small old screwdriver and try or make a tool
I haven't done this, so if you succeed, post pictures
With what I know now the No 1 reasons your coils F*ck up are:
1) your cylinder covers leaking oil into the spark holes
2) your Protective Cap BERU not isolating anymore (dry or full of oil)
3) 1 or 2 coils failing
I bought 2 used not functioning coil packs, left and right
DO NOT buy packs not functioning entirely
many of packs for sale have 1-3 failing only
the once I bought had one site 1 coil broken
1 coil 1-4 failing (this means most of the time only 4 coils broken on 12 !
they don't fail by pair
make sure the guy you buy them from writes what fails in ebay, just in case
I replaced the 2 smoked coils right side with one of the 8 good coils from the bought right side
I took the left bought 1 failing only coil pack and replaced the broken coil with one of my 6 failing left side
bingo ! 1 shot
so you see that even a retard like me can solder that
if you have replaced the failing coils and you would still have a problem, unsolder the mosfets for those cylinders and test them 'unfortunatly only way to test)
Do not waste your time with small economies REPLACE ALL YOUR Protective spark Caps !
replace ALL your spark plugs !
make sure your coilpack are well connected to ground !
clean interior of your coils with acetone or brake cleaner
use a very little silicone grease or special spark grease to lubricate the very end of your new Protective spark Caps
My final repair costs for both sides was 400 usd
sure you can get failing coil packs for less !
YOU WILL NEVER HIT THE LOTTERY IF YOU DON'T PLAY !
have fun !
NEARLY FORGOT:
Do not seal the coils again !
Use HIGH TEMP ducktape !
just a very little black gasket seal around the plug
that way you can reopen it anytime for repairs
if you need to replace the whole coil and his base
also easy mosfet removal
heat gun, keep the whole coilpack stable just in case
don't worry about the other components, they are varnish sealed
heat quickly by getting close and pull
once unsolder ed
let the plastic cool of before manipulating so it keeps his shape
you can also cover up places you don't want to heat up with aluminum foil or use a little metal plate
after this, prepare the mainboard with regular soldering device, add soldering
then put the mosfet on the top, heatgun again and it will go back to its place by it's own
I have repaired the coilpacks 100%
0 faults in das under full load
so it's perfectly possible if you have some courage and time
If you buy used coil packs to repair yours, make sure they have only 1-2 coils not working so you have parts
work by elimination and forget about it if you don't have Xentry /DAS or can't count faults
also, on another bonus pack, just for fun, I had coil 11 failing
switched coils,
same problem
so I switched the whole end of the coilpack with another one
bingo !

Excellent work here well done.
I see misfires under smooth running counter at idle on STAR. Are you saying a repaired coil pack shows no increments of smooth running on STAR aftewards?

I had coil 2 and 4 failing on the left, and some 1-2 fails, that is normal
mostly small fails are next to a really bad failing coil
I see! I have 1-2 small fails as you say, mostly on one bank. No misfires under hard load though, just these. Sometimes on cold start I can feel a few very light misfires but never puts check engine light on.

that is absoluteley normal
up to 4 misffires is more then normal (in DAS Xentry you can see that up to 9 misfires is nothing to worry about)
just means coilpack is not new

Ah yes I see!
On cold start number 10 on mine, increments very quickly, up to 19/20 but stops when warm. I can feel it in the car as well.
Is there any easy way to diagnose whether it's the coil pack , or voltage transformer , that's the problem ? Or is trial and error of trying and changing both parts the only way ?
