Latest N52K ECU software

rt7085 · 12-02-2021, 06:23 PM

Does anybody know what the latest and greatest software revision number of the motor controller ECU is supposed to be? This is for a 328xi E91 2008 wagon. Some BMW technician told me there was a specific update for making the engine idle smoother but I have no clue what revision that would be.

You would just have it updated in comfort mode with WinKFP. that revision is definitely really old. The latest one will be 0049QK0MM10SMGN3S / 8619538 or 0049QK0MI20SMVCAS / 8608328
