2011 x28i Laggy throttle and slipping feeling
I’m hoping someone who has experienced the same thing i am experiencing will chime in here. 2011 x28i with 154K. Here’s the scenario:
About a month ago i was pulling on to the interstate gathering speed up about 50mph and the X3 had what i thought felt like a misfire? Maybe a REALLY hard shift? A slip in the transmission? It did it once and i continued on cautiously. The next day, car was fine, I put it in manual shift mode and it is great. So iI started reading and googling and decided it was time to do the front&rear diffs and the Transfer case fluid. Ordered the stuff from FCP and a couple hours in the garage all the fluids had been changed. Art this point i reset the VTG. Now, after that was done..it feels like the gas pedal is very laggy…it seems as though the X3 is shifting at different points…and the car has been fine for a month until today…..on the way to work at about 45 mph, another big hard something…..i drove easy to work and when i left, car seems fine. Has anyone experienced something similar? I was thinking about changing out the transfer case fluid again just for peace of mind,,,… |

I don't know what your drivetrain issue is. I do know C90D60 AUC sensor isn't relevant. That's an air quality sensor located by your cabin air filter. I replaced mine this past summer.

If you are experiencing a shifting problem, I would do a tranny fluid and filter change before the transfer case and differentials.
