ignition coils - which is the right part number?

Hi,
my Z4MC has developed a bit of a misfire/reluctance to pick up revs low down in the range. According to my indy it is likely to be caused by an ignition coil being on the way out. I am likely getting ahead of myself here but I started looking at part numbers in case the issue is confirmed. I looked at Real OEM:
http://www.realoem.com/bmw/enUS/showpar ... Id=12_1104
and it looks like the BOSCH part(s) #12131712219 and #12137594937 have been discontinued and
the one manufactured by ELDOR #12138657273 is the correct one.
The discontinued ones seem to still be available on the market...Can anyone confirm or share what ignition coil they fitted (recently)?
Thanks in advance,
A

Either should be fine. I used Bosch just over a year ago, Eldor did replace them as OEM and from what I’ve read are very good quality so either / or would be fine I imagine though I’d get Eldor preferably.
Not so sure on the diagnostic though, what makes him think ignition coils is causing that issue? Not saying it isn’t but...based on what?

Hi,
thanks for the info. It would seem that the "old" Bosch ones are still available and are in EU while the Eldor seem to be available via USA only (at least on ebay).
Going to get the car properly diagnosed late next week (travelling for work prevents earlier appointment) so hopefully he will be able to determine the cause (fingers crossed not an expensive one)

Hello. Did you get this diagnosed and was it a fried coil pack? Which part number did you go for in end of that was the case?
I took my ///M out yesterday to take to a friends wedding, and she repaid me by developing knackered coil pack symptoms 30 mins into the journey !! I drive her less than 1000 a year !!!
I’ve read the fault codes and I’m getting “29D0” - combustion misfires, cylinder 4.
On ecp I see both the Bosch and Bremi ignition coils but not Eldor.
