Just had this error on a 2014 F15 X5. Beware. First SA said it must be replaced, and the bill was $1500. I said no, since as you see, there's no issue with drivability. I came home, reset the light with an OBD tool. But there were several errors that wouldn't clear.
Eventually went back for the fix, and was told by a different SA that "that shouldn't go bad" (about 50K miles) and got it paid for by BMW. The sensor insures proper exhaust temp to burn off soot.
According to the N57TU technical training doc, there are three sensors on the DPF: temperature, pressure differential, and oxygen. I imagine the most likely of the three to go bad would be oxygen but I am just spitballing. Do you have the ability to read BMW-specific codes to get more detail?
My 2014 328d at 95k is throwing two codes for the diesel particle sensors, 2BB600 and 2BB400.
There is a TIS that addresses this and extends warranty as well.
Covers F02, F10, F15, F25, F30, F31 models.
For the eligible vehicles, BMW of North America, LLC (***8220;BMW NA***8221 is extending the limited warranty for the vehicle***8217;s diesel particulate sensor to: 10 years/120,000 miles as determined by the vehicle***8217;s original in-service date
Just found the info, I'll proceed to contact my dealer and will report back on progress.
