today i had a problem with my Crank Ventilation Valve, i believe its just 2 pieces of caps that go by the engine, apparently they had some cuts in them, so the air/fuel mixture was not proportionate. I didn't get any faulty codes, until recently "Increase Emissions" in the IDRIVE. So those Ventilation Caps were replaced, and i've not noticed that surges so far between 30-40 m/h, although the rough idle hasn't gone away. Will monitor it for 2 weeks to see if it comes back again.
