Cocktail of 3.0i Trouble Codes - Where to Begin?
I read several posts about a faulty idle control valve being the source of this problem, so I installed a brand new one in a desperate attempt to clear the code. The original had 18X,XXX miles on it and was cleaned once before, so no harm in replacement at this mileage anyway. Here's my current list of codes, where do I begin? Haha. Smoke tested the intake, no leaks found. P0313 P0161 P1092 P0158 P0313 PD Wondering if this is a bad bank 2 sensor 2 oxygen sensor. Here's the car in question, out for a blizzard cruise the other week... https://youtu.be/5CFdYNxKsK4 |

Start with first code listed and work down.

Are you able to view live data? Short term, long term, 02 sensor voltage, MAF airflow in g/s. I wouldn't be changing the 02 sensor before seeing what kind of live data they are reporting.

Would you mind defining each code? I'd like to help, but I don't want to look them all up.
And I don't suppose you have a BMW-specific scanner? just P-codes? Were all these codes there previously? or did they just pop up? Was it only P1093 previously? |

Check MAF g/s values first. Should be in the 3 g/s at idle with no additional power draws, i.e.: no AC, lights, radio, blower fan, etc. 4g/s is too high
Secondly check your fuel pressure, should be around 52 PI Max.

99 Oyxgen-sensor voltage behind cat converter, bank 2 EB Trimming, oxygen sensor before cat converter, bank 1 BF Insufficient heat output, oxygen sensor behind cat converter, bank 2 F3 Misfire, cylinder 6 F2 Misfire, cylinder 5 Checked out the other readings: Idling the car with lights on last night, voltage at air-mass flow sensor 0.9 V Air mass reading 18kg/h while idling Air mass reading 44 kg/h at 2,000 rpm Air mass reading 55 kg/h at 2,600 rpm Finally, the oxygen sensors: Bank 1 before cat: voltage 0.11 to 0.76 V Bank 2 before cat: voltage 0.11 to 0.76 V Bank 1 after cat: voltage 0.11 to 0.76 V Bank 2 after cat: voltage frozen at 0.58 to 0.59 V Voltage appears static at the bank 2 oxygen sensor after the cat, when it should be fluctuating up and down like the other 3. |

Additional info from the data stream:
adaptation, mixture, additive bank 1: -0.11 ms adaptation, mixture, additive bank 2: -0.02 ms adaptation, mixture, bank 1 multiplicative: 5.8% adaptation, mixture, bank 2 multiplicative: 6.9% |

At your mileage, having done a smoke test, and with those codes. I'd replace all 4 o2 sensors as a matter of maintenance. You already did the fronts, do the rears. Reset adaptations and go from there.
