Yes, there is a PDF file here:
https://www.bimmerfest.com/threads/f...-guide.811347/ Maybe injecting CAFD is enough but I would have flashed it so you eliminate possible corrupted wrong SW. Modules can be different i-steps so won’t need to update whole car. Only the faulty ECUs and pick a i-step close to your current one if e-sys doesn’t show the exact one you have.

Did you VO code all necessary module FEM, HU_CIC/NBT, ICM, KOMBI, and AHM(if present)?

All modules were coded with VO.
e-sys 3.40.2 As soon as I start to calculate Tal, error pops up, any idea? WARN events: "[DME_BAC3 - 12] Warning 2270, Error while checking if ECU supports delete SWE: job failed with negative response error: code: service returned global negative response description: Service RDBI_ESDS returned a negative response with response code requestOutOfRange: LinkName: DME_BAC3 12 ETHERNET severity: ERROR (Exception: null) " [C382] Problem solved, I've just bought another two radar sensors that replaced previous, and current it's working finally. :-) Last edited by Robibig; 03-06-2024 at 01:40 AM.. |

Got delayed with finishing up the blind spot install. But just to plan ahead, did anyone have any issues calibrating the radars? I watched the official BMW video and obviously I will not be able to have any of the specialized tools they used. So what things should consider? Make sure there are no reflective items (or any items) behind/near the car while doing the calibrating routine in ISTA+?

If you watch the video, I doubt there is an aftermarket equivalent out there. So my question is: is there a particular way to do the calibration or it works itself out somehow?

Flexray initialization is often separate procedure in ISTA In worst case you have to go to the dealer and ask them to do it. |

There are aftermarket solutions to calibrate the front facing radar for ACC, so I imagine there are the same for blind spot radars.

Flexray is like canbus and linbus, in other words a communication protocol. Radar is a whole different technology and has also a very different use. |

No, not confusing Flex Ray initialization with sensor calibration. Read the first page? The OP mentions radar sensor initialization right after the second flex Ray initialization. Wondering if the sensor initialization was actually sensor calibration.

Apparently, if nobody here had any issues with the radar sensors properly detecting objects after installation, then, as long as you have installed the radars properly in their holding brackets, the sensors receive a default value during calibration, which seems to work.

OP never mentions calibration, I’m just confused where you got the idea that a special calibration sequence was required for this retrofit? Furthermore, you mentioned doing the calibration procedure without proper equipment, which would undoubtedly be worse than leaving as-is.

The OP says radar sensor initialization. What does that mean for you? For me it means the sensors are given a signal detection signature baseline. Just like when you initialize (calibrate) your windows roll up/down. Have you done one of those? What do you think that accomplishes? Have you ever done radar sensor calibration of your PIR security lights or house alarm? Very similar concept but simpler. There you adjust for the distance and direction and speed/size of object. Clearly these sensors are to be calibrated as shown by the BMW factory training video. The question I would like to answer is if it’s something that can be done without the proper equipment and it still works as intended. If yes, the car has to be likely away from any radar reflective objects. Apparently, if people actually completed this DIY and experienced no issues after calibration then the BMW factory calibration procedure is an overkill.

I haven’t done this retrofit as I don’t own this particular car but could it be that initializing and calibration are 2 different things? Anyway to be sure I would just initialize it on a empty parking lot or other empty space. I think it will be fine. This is just a thing you should try and find out instead of contemplating / prepare beforehand as this isn’t really a common procedure and requires extra equipment. Like I said, in worst case you have to pay the dealer 1 or 2 hours of work But I don’t think you have to because otherwise more people would have talked about it here.

Out of curiosity I poked around in ISTA and I did find something which hinted at SWW procedure but was unclear what it did, as it was greyed out since my car was not connected.

Most likely since the sensors go in a certain way inside the brackets, they should be properly oriented anyway. And the software probably applies a standard programming that already has pre-calculated parameters. Maybe this calibration process is something they would do after an accident, but probably even then it’s an overkill.

Finally had time to finish the LCW project. I ran into some problems, and thanks for an earlier post about using Tools32 on flexray-setup I was able to get HC2 ECU to show up in ESys.
I have one error still: D90D19 – Assist system operating unit (BEFAS) (LIN): Incorrect version installed Incorrect driver assistance system operating facility variant detected Check encoding Install correct BEFAS version That is likely related to me tapping into the headlight switch power/ground/k-lin, because my car seems to be the only one that does not have a hidden LCW plug next to the headlight harness. So I am using the K-lin 8 pin on FEM for the headlight, while the LCW uses the same K-lin 8 bus, but pins 37/38/39 of the same FEM 7B connector. So the car expects the lane assist switch on the 37/38/39 bus. One thing I was not able yet to figure out. How to change the LCW minimum speed detection down to 17 mph from 30 mph as described. Bimmercode's Expert mode does not have the 3000 ICM C-ZSW_Aktivierunggeschwindigket_Funktion_low . Will check Esys, although I never FDL coded in ESys.
