You won't get any codes regarding this, and swapping them from cylinder to cylinder won't change anything as your whole pack is weak. Your plugs will need to replace same time as well, and highly recommend not using the OE bosch. Only use NGK or OEM BMW Bosch.
Also, don't just start doing adaptions and calibrations. Those are only meant to do when replacing and installing new parts for those certain items. It is not good for wear as it resets calibration on them as it has zero wear/new part.
Here is more information regarding the trash bosch plugs. https://f15.bimmerpost.com/forums/sh....php?t=2014403 |
I really hope it's as simple as coil packs. So you had similar symptoms as mine where its random cylinder misfire? And thanks for the heads up on the adaptation/calibrations.
And looks like I'm running Bosch ZR5TPP33. I'll order a set of NGK 97506 and swap them later. The Bosch coil packs should be delivered tomorrow.
Thanks!
