As I understand it this is an O2 heater circuit signal issue and not necessarily a faulty O2 sensor.
I replaced both my precat O2 sensors about a year and half ago on a 2008 MSD81 135i.
Beginning to conclude the DME may be the root cause of the signal interuption/failure.
Can anyone recommend a good vendor for replace/reprogram an MSD81?

Follow up to this issue........Had to clone and replace my MSD81 DME through a company called G-Coding. Have been running code free since doing so in January
