Codes: 2883, 2882

SES light comes on my X3 2005, 3.0 and codes 2883, 2882 (mixture preparation Bank1 and Bank2) pops up after scanning for error.
Engine sometimes runs slightly rough when in parking or neutral position. Also codes 2746, 2747 and 274E, which means cylinder #2, cylinder #4 and all cylinders misfire showed up several times.
I've changed all spark plugs, oxygen sensors 1 & 2, air intake boot, air filter, gas cap and inspected DISA valve. Also did reset SES light, but it's coming back after about 50 miles of driving.
Any suggestion?

How many miles on it? Crankcase ventilation parts been replaced yet? May not be related to the misfires, but maybe the mixture prep codes. I'm struggling with a similar issue but without the misfire codes, just a bad loping idle. trying to figure out how to measure fuel flow,not just pressure on mine to eliminate that.

yeah, good thread under x3 forum titled "ccv and oh disa" or something like that, i searched ccv i think. quite a pain, i got everything taken apart last night and am getting ready to put the new hoses and oil seperator on. it's so buried that it makes you wanna take the whole intake manifold off but i don't think you have to and then you'd really be in deep.

at 95k I would almost bet your CCV is toast, what are the generic OBD codes? my CCV failed (hole in a hose and broken valve) and threw a lean bank code on both banks, I had a severe loping idle when cold and a slightly loping idle when warm, felt like it was missing. the shop I took it to removed the intake manifold to do the job, but you CAN do it without doing that, its just more difficult. I also replaced my intake boot at the same time, it was ripped on the small bellows.

Just wondering why everybody pushing for CCV? If something wrong with crank case ventilation system there should be different codes: 2FDA and 2FDB as reflecting in Peake Code Reader manual.

I never pulled the BMW codes, all I know is when mine failed it threw lean bank on both banks and it ran exactly like you are describing AND thats the only thing you have not changed...kinda narrows it down
do a search on the E46 side, those guys get all kinds of crazy codes when the CCV fails

just finished replacing my ccv system and my problem is NOT solved....
-the misfire codes that you have are troubling, i never got those. did you try replacing the coils on the cylinders that are showing misfires?

No, I did not replace the coils. The codes 2747 and 274E gone by themselves....I did change CCV also, but codes 2883 and 2882 still remaining....

good to hear it was a simple repair, where did you get your new IACV at?

codes 2883 2882

hey .. i have a 2006 x3, has tsb for these faults for no oe filter , have replaced the filter and the ccv , then smoke tested intake no leaks, no one has ever replaced a mafs for this problem, i am a technician, why the idle air control valve ? what does it stick open for a second and let too much air in for a second, and send the vehicle into somekind of limp home mode? just curious before i throw a part at it,it just slides into intake next to t body right?

if it wont idle and you have the same codes, i strongly suggest putting in the iac. it is not easy or fun but not terrible and its the most likely cause. not sure what happens to it. good idea to have a new air intake boot if there is any wear on the original.

yes, location is correct, kinda a pain to get the other intake blend control motor off and out of the way first.

damn 2883 2882

i was so excited to hear of the iac repair i went straight to work the next day and replaced it, i didnt have an idle issue but thought maybe it was sticking or not moving quickly enough, replaced valve reset codes, reset monitors, vehicle drove completely different more responsive and shifted like it did when i got it , then two days later call from wife , cel back on again, same faults.. i have a freind at the local bmw dealership and will be taking it in on monday, to see if it just needs updates or possibly i have the only x3 that actually needs a mafs, cant wait to get this figured out . will be in touch with the actual repair.
