2012 X6 Cylinder Misfire & Deactivation

[MadHatx6]

Hey so my bmw started misfiring and I’ve gotten a lot of different codes. The reoccurring one is that the 3rd cylinder has been deactivated due to misfire. I’ve also had codes about the absolute manifold pressure sensor, throttle body angle, and the valvtronic sensor malfunction code. These three seem to come and go randomly. I’ve already troubleshot all cylinders and they all point back to cylinder 3. After further investigation, found that the spark plug and injector was shot, so I’ve had that replaced including the coil pack for it. I STILL have a misfire on that cylinder. I’ve had the voltage checked on all the wiring that leads back to the ecu/dme and it all checks out. I am currently in the midst of getting the ECU replaced & reprogrammed, what are the odds that THIS will finally solve my problem??? 😭😭😭I just want my baby back to running normal!!! Please help. Any advice or insight would be greatly appreciated. !!!! 🙏🏾

Carbon buildup....

Nah it was the DME & not the ECU....so I basically just pissed away $320 to get that installed & programmed. JUST to find out that I have to get a new DME installed & programmed instead. GREAT.
