Do you have inpa ? , you can see device connected in MOST ring, and do some initialisation... Quote:
MOST GW is built in NBT, you can code Kombi only with most ring connected, so kombi cannot be coded through PT CAN, like basic kombi. Quote:

I'm trying to retrofit a 6WA kombi on my BKOMBI car.
Those who tried to retrofit the 6WA and couldn't detect it, I might have a theory, but no way to test it till I get my Kombi. I agree you need MOST Cable for all the MM stuff, Service information and Diagnostics, but you don't need it for flashing or detecting the ECU. I think I know why you can't detect the new KOMBI. I don't think you need to upgrade the FEM_BODY MAX/HIGH. Both BKOMBI and 6WA Kombi uses FA_CAN to communicate to the car (FEM), only difference is 6WA has MOST as part of the Bus type for other information transfer. Check picture 1 and 2. Fist Picture with 6WA Kombi on Aritaurus's SVT and Second one is BKOMBI from my base car. I was playing around with the SVT Target (what's written in the car's VCM) and SVT Actual what you have based on the ECU's you have in the car (Including anything you added). The reason I think you cant detect the New Kombi is because both BKombi and 6WA uses the same Hardware ID but different name. In this case ID 60. So when you Read SVT from SVT Actual it picks up the Information written in the VCM of your car, which has Hardware ID/name of the BKOMBI but in fact you have connected the 6WA, but software related to that is not relevant. It will still show you BKOMBI ECU information in the SVT tree. We know this already, which is why we inject the CAFD to the kombi, as per what we need to do. I think it fist reads VCM ECU and then whatever is connected to the car actual ecu, but if there's a conflict of Hardware ID, it defaults to VCM ecu relevant to that ID, regardless what you have connected. I think all we need to do is make a backup of your original SVT Target and edit/delete out the BKombi, write this back to your VCM and then read the SVT actual from the car. This should in theory show the 6WA. Worse come to worse. You can always write back your backup SVT target back to the car. If you still cant read it. Maybe one of you can try this out if you had no success reading the 6WA. Correct me if i'm wrong guys. From all the analysis, this is my understanding. |

But maybe those cars already had FEM_BODY MAX/HIGH due to another option like Adaptive Headlights.

Why? Coding is simple with proper hardware and installation. Just add 6WA to FA, and VO Code Kombi. Making an FDL Code comparison to a stock 6WA car is not necessary.
The issue here is getting E-Sys to recognize instrument cluster properly as Kombi and not BKombi, so it can then be coded.

It's for the second part of your statement, when E-Sys insist on using BKOMBI instead of KOMBI. I meant to say it's easier to modify FA by changing parameters than deleting the ECU altogether.

The problem lies at the hardware level causing SVT not to recognize 6WA cluster, even with 6WA in FA.

F30EDR, I think FA is just a guideline for SVT's. FA informs SVT's, what options they have to turn on/off based on the Option list.
Last night when I read my SVT actual, my SVT tree showed TBX and ZEB3 modules. I never had these in my CAR, but yet they showed up (I was using a Donor vin to flash my NBT FW, donor vin/build date contained TBX and ZEB3). When i backed up my SVT target from VCM, it had TBX and ZEB3 modules in the list. What I did was write back my Factory SVT target (from a backup) back to VCM and then read it again, now it only showed what my actual list was. Which is why I think SVT actual is not reliable, As it composes whats written in VCM and any other ECU not conflicting with hardware ID. If there's a conflict, it presents what's in VCM For example, ZEB2 was connected to my K_CAN and working. But my SVT list showed ZEB3, hardware wise ZEB3 is supposed to be connected to BODY_CAN bus, but with the same hardware ID as ZEB2 (103). So what my point is, it doesn't matter what Bus it's connecting to as long as ID's don't conflict we should be able to get 6WA Kombi working. SO now I tried this in my car. Deleted my BKOMBI from SVT target list and wrote that to my VCM. for a few second my KOMBI stopped working. Then came back online. I read the SVT actual, it showed all my ECU's. Then went back to my SVT Target and did another backup Edited the XML guess what. BKOMBI wasn't there. But yet, SVT actual was able to compose the list based on VCM and whatever is connected to my bus. |

Shawn, has anyone confirmed that, there is a FEM MAX/HIGH avaliable for F30? I keep comparing parts on etk, and all I see is hardware revisions/build (D5, D6, D7.1 and D7.4).
It sounds to me like FEM Max/High doesn't exist. As I have also compared the software/hw ID's of Aritaurus's and my FEM (we both share the same production month and software update recently), they both are the same. His car has Xenon's and Extended Kombi, but yet he has the same hardware. |

I am not sure what is meant by "FEM MAX/HIGH". Like you, I first heard of this in "BMW F30/F31 Xenon retrofit" thread.

Hi Vithy,
Do you have any 6WA retrofit update which can be shared? Since my coder had tried remove the BKOMBI from VO and added the new 6WA in, but same issues as before. The retrofit is still not successful. Thanks a lot. |

Hi mougwai
I see you have done a retrofit 6wa on a f30. Could you tell me where the EEPROM chip is on the f30 6wa as its different from all the guides? Thanks |

Guys, thanks a lot for sharing all these info.
My cluster is on its way and it is used. Is there a manual on how should I kind of reset it before installing?? And what additional parts will I need? I understand that first of all it's most bus from head unit to cluster - what's the partnumber? Many thanks in advance |

Hi Serpent720, Sorry for the late response. I decided not to do it, Not really worth for me.
Have you done your retrofit? did it work? If not if you can get me your SVT_target and FA. I should be able to investigate. Further research makes me guess it's FEM hardware ID D4 and D5. New once are D6, D7.1 and D7.4. I know my hardware ID/revision is D5, if you have anything bellow D5, that might be the issue. You can do a simple test with your SVT. Under FEM_BODY, write down all your HWAP_xxxxx's and HWEL_xxxxx's, this is just to see what is currently in. Under TAL calculation Add 6WA to your FA and using your istep shipment do a calculation. Under FEM_BODY, if your see HWAP_xxxxx and HWEL_xxxxx anything new added from the old (Actual will be blue - what you had, Target will be red - new hw ID's) , then there is a hardware difference in FEM. If you dont know how to let me know I can check. With my FEM (D5), i dont think i need to get a new FEM to get 6WA detected. For fun, I added 322 (comfort access) to my FA, and did a calculation. My HWAP and HWEL changed. This tells me for Comfort access I need a different FEM. Good luck. |

Hi Vithy,
Thanks a lot for your information. I will try again this weekend, and will try to align the HWAP and HWEL matching the original value and retry the retrofit. Will let you know the results. Cheers |

Serpent720, don't really worry about HWAP, just make sure HWEL is not changed. Cuz thats the actual hardware ID.

I flashed a MY13 F30 with Xenon's and everything else exact as my MY12 F30. FEM was exactly my revision FEM MID. Compared the hardware ID's using his svt to mine also those matched. On a different F30 MY12 when we did 2TB retrofit so removed one of the connectors to run a wire to the steering and noticed it had FEM HIGH. When I compared the SVT it had comfort access. I think since comfort access requires additional connector pins and hardware within FEM, which requires it to have FEM HIGH. If you are planning 6WA and Xenon retrofit, your FEM Should be good. |
