HELP: Smoke, Noise and Rough idle after engine swap
Hi folks, looking for your help, hopefully you can steer me in the righ direction as I am in dead-end how to troubleshoot it.
Context: I did an engine swap on my 2006 325i. Instead of rod-knocked N52B25, I installed N52B30 from 2006 330i. Everything went fairly smoothly, in addition I did a bunch of service to the engine (new water pump, thermo, valve cover gasket, oil pan gasket, new drive belt and pulley, new sparks, coolant, power steering, oil, tranny oil etc). When I first started, at first it cranked a long time, then evetually started, but with some odd noises and after a few seconds some smoke from the exaust maniforl area. Here is the video: Also here are the codes pulled after the start: Engine module for N52 Current Fault Codes 2A82 inlet-Vanos variable cam control test Error will cause a warning light Error is not currently present Test conditions have been completed 2A98 crank shaft - inlet camshaft, correlation Error will cause a warning light Error is not currently present Test conditions have been completed Short circuit or signal interruption 2E69 knock sensor signal 2 Error will cause a warning light Error is currently present Test conditions have been completed Short circuit or signal interruption 2AE4 motor venting/heating relay, input signal Error will not cause a warning light Error is not currently present Test conditions have been completed Timeout 2E68 knock sensor signal 1 Error will cause a warning light Error is currently present Test conditions have been completed Short circuit or signal interruption 2DEC power management, battery control Error will not cause a warning light Error is currently present Test conditions have been completed Signal or value below threshold 2E1B ignition, cylinder 4 Error will not cause a warning light Error is not currently present Test conditions have been completed Signal or value below threshold 2E19 ignition, cylinder 2 Error will not cause a warning light Error is not currently present Test conditions have been completed Signal or value below threshold 2E1D ignition, cylinder 6 Error will not cause a warning light Error is not currently present Test conditions have been completed Signal or value below threshold 29D0 misfirings, cylinder 4 Error will cause a warning light Error is not currently present Test conditions have been completed Signal or value below threshold Electronic fuel pump (EKP) Externer Fehler: CAN-Bus-Off Error will cause a warning light Error is not currently present Test conditions have been completed Any help is appreciated!
