Does anyone have any information on this particular Bosch ignition coil for BMW. The part no. is 12131712219. Tried googling it but was couldn't find much info. I would be really grateful if anyone here can help me out.
I think I should provide this information as an answer to highlight the correct pin-out obtained from Bosch for any future members who wish to do a rewiring or troubleshooting.
I wanted to give an update to this answer. I didn't go ahead with the wiring mentioned in this post as I wasn't fully confident if that is the right one. Also I was concerned that it might damage my ECU if I wired it wrong especially since this has high voltage present.
I had contacted the Bosch Global team but they could only get me a catalog and other data for the coil, nothing related to pinout. Next tried contacting the Bosch USA but they just directed be to their Bosch India Auto parts, yet to hear back from them after to weeks. Finally I contacted their Middle East team who told me they would contact the engineering team and get back with the pin-out. After a week finally they have provided. Here is the correct pin-out from Bosch:
