Whilst ive been trying to sort the many faults on my p38 I have pulled a fault code regarding the o2 sensor heater curcuit both banks
O2 Probe Heating before Catalytic Converter - Minimum Value Not Reached.Fault Present and Static
And the same fore bank 2
Ive checked voltage on the harness side and both are getting 12v
Checked resistance on the sensor side and thats fine also
These were replaced not long ago aswell
Scratching my head a bit on this one

I got them for eurocarparts, they were under 40 quid. You do need to cut wires and re-join but everything comes in the box from bosch. First one took me about 20 mins other one 10 mins.
