2013 BMW 650i F12 MSport - Permanent miss-fire on cylinder 7. Replaced all coil packs and plugs with no change. Sent the 2 - DME's and 2 additional modules + key and they were able to determine my issue was a burnt ingnition driver on DME2! They repaired it and shipped eveything back very quickly! My car is running perfectly now!
Thank you ECU Pro!
