Chasing P0172 and P0175 System too rich codes
I have been chasing 2 codes on the X5 P0172 and P0175 system too rich codes. I replaced the MAF with a new VDO unit from FCP Euro and both pre catalyst O2 sensors. Didn't have a single code for 8 months and now it's back.
My MAF seems to read high at idle at 4.7-4.8 g/s with all accessories off (A/C, radio, lights, etc) Can anyone let me know where their M54 MAF runs at warm idle?
