I'd look for the two wire in your trunk area circled in the photo below...and if it does not have an Aerial on it, then you can find one off eBay for a good price ($15'ish), or you can get them from a BMW dealer fairly cheap ($50'ish). P/N 65209220832. This aerial is for your comfort access. Last edited by M_Bimmer; 01-02-2024 at 09:10 PM.. |

Also, what are those custom wires hooked up to the battery? On-vehicle battery charging should be carried out via terminals under the bonnet. |

One of the things I have been thinking about doing is a smoke test. I can get a cheap one for 10 bucks but I don't know where to hook up the tube from it on this vehicle. Do you know where I can connect a smoke tester supply line on this engine? |

For luggage compartment aerial, 'existent' tag no longer shows 'yes', but 'no'. To me it indicates that this problem is resolved. I was wondering if any of comfort access functions were working, or was only luggage compartment lid with car locking function out of order. Many errors do not clear automatically, but initiate a logistics counter. This will start counting down every vehicle start where error has not occurred, and if it reaches zero, then error is erased automatically. Other errors might not even have that and can only be erased with diagnostics equipment. What I would like to focus on now is the most pressing issue of lean running conditions. We can address other faults in there later on or in a separate thread; just to keep our focus on issue at hand. Now, if you calculate a test plan for mixture control and run through it's initial steps, where does it lead you? I see that you mentioned you are already running through this service module. If it is information based service module only, then you can run it all off the vehicle. If it has some interaction with the car then it can only be launched when connected to vehicle. At any point, if service module requires connection to vehicle then you will be made known of it via the module itself. Where can you get one so cheap? I hope it's not a sarin gas machine. I would have to study the intake runs of your particular engine a bit. It's not like the old cars where there were no restrictions along the whole intake run. With these engines, one must make sure that air and smoke can actually pass to all parts that need testing. |

As far as the smoke test, Walmart online and other places sell a type of "bellows" contraption w an input tube that sucks on a cigarette, and an output tube supply line that you connect to your vehicle. I can post a link to it if you'd like. I figure for that cheap it might be worth doing an immediate smoke test to rule that out, what do you think? My only question is, where do I hook up that small-diameter tube on this intake system? The machine ones that I've seen on Amazon and elsewhere have a large cone-shaped end that go right into the large-hole intake on the engine, essentially creating an air-tight seal as it pumps smoke into the engine. Adding this as an edit to my post.... I have seen a YouTube video where a dude wrapped a rubber work glove to the large air intake and poked a hole in one of the fingers, inserted the smoke tube and used a zip tie to seal that and another zip tie where it wrapped around the intake.

Here is what I pulled from TIS: Intake air temperature sensor An intake air temperature sensor is usually integrated into the hot film air mass meter. The hot film air mass meter is omitted for various motorisations. Note! The hot film air mass meter has already been omitted for various engines. The volumetric efficiency is calculated by the engine control from different signals using a model. In some country-specific engine versions an intake air temperature sensor is installed instead of the hot film air mass meter! Observe the Electronic Parts Catalogue and the wiring diagram! The intake air temperature sensor detects the temperature of the fresh air compressed by the exhaust turbocharger and cooled by the charge air cooler. Functional description A temperature-dependent electrical resistor is used for temperature sensing. The circuit contains a voltage divider where the resistance can be measured depending on the temperature. A temperature is converted using a characteristic curve specific to the sensor. An NTC resistor (NTC) is installed in the charge-air temperature sensor, whose resistance value drops when the temperature increases. The resistance changes from approx. 106 kΩ to 33 Ω depending on temperature, which corresponds to a temperature of -45 °C to 160 °C. |

Do codes 118001 and 118101 both indicate same bank?
What I would do at this point is swap pre-cat O2 sensors between bank 1 and 2 to see if error follows the probe. |

Regarding the MAF sensor on that side, I need to find out what this engine uses to measure air on that side since apparently this doesn't have a MAF. I gotta imagine that part was damaged by the ingested H2O. Bimmer did send that info up above about an air temp sensor doing the work for that, so maybe I need to look for that? |

If it was me, I would just go ahead and replace the temperature sensor, both MAP sensors and both pre-cat O2 sensors. It's just that I dont have confidence that these sensors are accurate enough after water injection. Even if sensors themselves dont throw internal error codes then they still can be out of normal operating range. For me, it would be worth it as these sensors wont cost much and I would buy myself some peace of mind. Pre-cat O2 sensors you have to replace at some point anyway, and when you do, you always want to change them in pairs, not just one bank. As M_Bimmer stated, you dont have MAF sensors. Kind of makes sense to omit those from vehicles. They really aren't needed anymore because very accurate information can be estimated using manifold pressure and calculation models in DME. Especially considering EGR and valvetronic systems, mass flow measurements would not be particularly meaningful anyway. |
