    2008 was pre-facelift so would need a replacement regulator. Remember the battery management moved from it's own module to being on the gateway, and that uses a different signal.

    That’s correct and v6 engines needs entire generator swap. For 2.0 R4 just regulator will do. This is due to different construction of the alternators.

    I just changed the regulator on my V6 TDi engine, there were two possible alternators for the V6, one was Bosch and the other was Valeo and I was just able to replace the regulator on my Valeo unit. It could be the Bosch required a full replacement.

    this means that i`ll have to get someone to change the alternator and have the new BEM installed and wired at the same time. I`m driving for almost an year with the old BEM and facelift gateway, but im tired of the error codes in engine, can and radio...

    Yeah you will need get rid of BEM on the back, run cable From pin2 of your gateway to the battery with new “minus” clamp to pin1. Elsawin will tell you the details but surely you need a single wire from pin2 GW to your boot and take it from there. No wiring change on generator itself. Just a swap.
    Lee is right - I forgot about Valeo thing :)

    I did that when i was installing the camera video feed to the head unit, also i have created an adapter harness to plug into the 14 pin old plug of the prefacelift BEM. Just to point that you can tap into the wire on the lower part of A-pillar.

    I have all set up and waiting, except the alternator. I went to the dealership but they could not tell me if i have bosch or valeo unit. It has to be checked under the car...

    Hi B5Nut, perhaps you could help me out as i am bit out of ideas...i have '09 C6 with a 3G High and have done the retrofit to 3Gp. The unit comes from a Q5 but it was previously installed in an C6.

    My problem is that most of the features are greyed out and so far i've come to the conclusion that i would need to flash my CAN to 0035 SW version, is that correct? My CAN currently runs on 0024SW version.

    Also, i've got AAS and the menu only come up if i use Q7 in the green menu, if i use C6 it will not show on the MMI. Car and Tel buttons are reversed, is there anything that cand be done to sort these out as well?

    Unfortunately I cannot remember what the software version of my gateway was, it's been almost 5 years since I did the install. I do know the gateway I used was from a late model Q7 4L.

    You need the 5F module in Q7 mode, A6 won't work as that it's for the later C7 model which uses a higher speed can system. The old Q7 4L had 3GP and it basically the same electronics & CAN-BUS as the C6.

    Nothing you can do about the buttons being revered.

    Here is a link to remove 2 of the fault codes https://upgrademyaudi.net/tutorials/03276-please-check-software-version-management-how-to-remove/

    I had fault code 03278, don't think you will ever git rid of that fault.

    after trying different configurations today i have made some progress, as in it all works but the Time and Service Interval which are greyed out and now i am really hitting the wall as i can't seem to be able to find the right configuration within the Green menu for these last 2 features, any suggestions?

    Definetely if i put 0 in the carmneuoperation the functions do not show up at all on the MMI, if i set it as i should they show up but greyed out. I can only think that the secret lies within the checking or un-checking it in the cardevicelist and carprotocolswitch, but then when you ad the carbusassignment the list of possible combinations is quite very large....

    For the clock to work do the following.

    - cardevicelist -> select "clock"
    - carprotocollswitch -> "clock" not select

    Thanks B5Nut for taking your time to answer, i got it all fully functional now with a combination of checking and uncheking in a few places in the green menu plus carbusassignment.

    There is one more thing which i am missing, but i think this is due to the way the newer system work, on the old MMI 3g High i had the option to configure what the onboard computer shows on the IC. On this this MMI 3gp i don't find such an option, have looked in a mates C7 and it doesn't have it, not a big deal since i had everything checked anyways so i have the full info on the IC.

    Are you referring to FIS/cluster options configurable via MMI?
    If so - after 3GP retrofit that option is not existing so nothing to worry about.

    yes, that is the one i am referring to. I thought so too that is no longer available, so how would you go about configure that if you wished so? As i said, i don't need to do that, just curious what would be the route...

    Think you can change the setting using VCDS in the cluster.

    the problem with the incorrectly labeled buttons after the retrofit to 3GP can be sorted by getting an MMI controller unit form a Q7 facelift and swapping the buttons over to the C6 controller, they fit 100% our panel...so i am now looking for one :)

    Good luck with the search. when I was looking at them 4/5 years ago they made strong money and not worth it for a couple of buttons.
