Previously, cleaning the idle control valve resolved this issue for us in 2016. Well, 42,XXX miles later and the P1093 code is back on.
M54 ICV cleaning video: https://youtu.be/lVPV-XnmJyk Just replaced both pre-cat sensors again, no luck there. |

Cleaned my MAF with MAF specific cleaner, put a big bottle of Lucas complete fuel injection system cleaner in the tank. Drove 130 miles this week, the light came right back on.
At 132 miles, the service engine soon light turned off on its own! The code was gone for about a day, several drive cycles. Then it returned. I thought this was quite unusual. Anyone have some insight? |

Update on this issue: I used a $75 smoke tester kit (found on eBay and Amazon) to smoke the intake on our X5. Through a glove on the air intake, in front of the MAF. Removed the MAF to avoid any potential damage from the smoke fluid vapor.
Here's a video of the smoke test kit/process I used on my E32: https://youtu.be/QIGQGai5ngs After about 10 minutes of smoke building up, it began to pour from a vacuum hose attached to the lower intake boot. For some reason the vacuum line was barely on the fitting, and smoke began to billow out. Definitely a leaking spot. Pushed the hose back on, and done. Erased the code, will report back when or if the codes return. If the code does return, I've purchased a new Bosch Idle Control Valve for around $175 at FCP Euro to install. Several people have reported a faulty ICV causing this code and issue. |

The SES light came back on within 37 miles of erasing the code and fixing the leaking vacuum line. New idle control valve will go in this weekend... sigh...

I was excited for you when the smoke tester "worked" so I built myself a little tester and was hoping that would point me in the right direction chasing down my misfire. Hopefully the ICV is the answer for you (fingers crossed) |

Hey everyone, bad news. Installed new ICV Sunday and erased the code.
24 miles after the installation of the new idle control valve the service engine soon light returned. Not sure what is next. |

Is it still the same code? What are some of your data when the light comes on? STFT, LTFT, MAF air flow g/s?
