    Actually, looking at that photo, it seems like it has 4 video inputs in the control unit. I'm not sure for certain, but it looks like that unit is for the surround camera package?

    Edit: Ah, SOS. You have a completely different control unit in that case - my car is 2017 and I don't have the SOS.

    @GenerationGav do you have MMI Plus (tech pack) or virtual cockpit?

    Yup - it's the only thing like that. Appears that it's definitely the right plug (T54A) but I've just not got anything currently going to the two correct pins, so nothing to splice into.

    Are any of the cables going into that plug brown + orange?

    Yes - one is. Will have to go back shortly to check which PIN it goes into. Suppose I can try to mark that back to the circuit diagram

    I see, okay. If there is also a single grey wire, I believe it would be safe to assume they are your CAN high / low.

    No single grey wire. Otherwise I might have presumed them and not checked the actual pins anyway.

    Bummer. I don't believe I'll be able to provide any more help then, my guess is as good as yours. Maybe @DJAlix would be kind enough to give you some info.

    Actually, if pins 2 and 10 are occupied (red wire, orange/brown) I believe they'll be the ones.

    I'll check shortly, but 10 is listed as Engine Control Unit, so just wondering why you think these PINs.

    They were the listed pins for the surround control unit.

    Got nothing going into 2, red wire into 10 - but looking at the surround control module that actually goes into 12 and 30 on the CanBus.
    As a last ditch attempt I "shoved" the wires into 12 and 30. I've now got a reversing camera module on ODB11. Although not working as the video pins aren't yet plugged in. I think I need 2 pins for the J54 plug and I'm done. Hoping another post will help me find these.

    And - it works!! Image shows with guidelines appears to be all good.
    At the moment the CanBus cables are literally shoved into the plug, but appears to work. I've ordered some of what I think/hope are the right pins. Paid over the odds for them, but all Audi parts places are obviously closed. Otherwise I'd be a bit worried about reliability.
    I've currently got no lumbar support adjust as I didn't realise that the fuses were smaller. Does anybody know what size fuses I need to get? Car appears to use 3 sizes...
    Few things, the cables were too short to get the MMI out properly, so I actually unscrewed the mount for it and didn't really need to use the keys - made it a lot easier to achieve.
    I'd have also bought some material tape if doing it again. Used standard insulating tape.

    Wow, that's interesting. Congrats, good job.

    I used either 5A or 7.5A I believe, I haven't had any issues with lumbar support.

    I used material tape for the cables, think it was a few quid off Amazon. Definitely a worthwhile investment. In regards to the MMI, that's what I ended up doing too. Took me long enough to figure that out though..

    Yeah, just seems odd that I didn't have anything in them pins. Just hope the ones I've got ordered are right.
    The fuses I had in the garage are too big, so.i "borrowed" the lumbar support fuse until I can get it sorted.

    Yeah - material tape would have been a good idea, but the insulating tape worked. Around the fuse box the cables take a bit of an odd route, but otherwise all good.

    If anybody needs then the code for the "PINS" which go into the CanBus controller are; 000979010E
    I found some overpriced on ebay, but at least I'm up and running.
    On another note, how do people find the accuracy of the red "end" line? I lined that up with a kerb or parking line and seem to finish really far forward.

    To be honest I only really use the moving guidelines when initially lining the car up. I don't use the distance measurement at all. I think you'll end up kinda using the lines for reference without even realising. I don't really notice them there any more.

    Great write up - wish I'd done something like that in hind sight, but I had to do it in between looking after a toddler so did it over about 4 days in small stints, plus was a bit nervous so didn't end up with photos.
    That AliExpress site is interesting and could end up costing me a lot of money!
    The washer version was available when I bought mine, but I spoke to them and they advised that it needed more kit - and possibly even a pump than just hooking it up to the existing washer, so decided against it.
    Interesting with yours been a LHD car that you had to pull the video line all of the way across the back seats to get it to the other side of the car, for mine it was left hand side for the fuse box and the glove box, making it slightly easier.
    I'm still not sure why I appear to be the only one who didn't have existing wires in Can HIGH and Can LOW, although it probably made the end installation neater.
    Nice work anyway!

    Nice job. I'm fitting the TPMS soon, also thanks to Alibaba. They've got some right bargains on there.

    It would have been really nice to have the washer jet in mine but I've got a saloon. Oh well.

    Amazing job. You've inspired me to do it.
    Question - will this work on a car without any existing parking assist features? I have no PDC, but with to install a camera.

    That guide will come in handy for the tailgate strip required to refit my Thinkware F770 Front/Back dashcam. I was wondering how the tailgate hinge pkastic covers opened up - do you just pry off with trim removal tools? Apart from that (usually feed through disconnected rubber gaiters on my Golf R and Polo GTI+), the removal of the tailgate trim seems as straightforward as the 2 aforementioned cars - a couple of T25 screws to remove and then pry with trim removal tools for the diamond shaped metal swing clips.

    I then run the wiring for rear cam along the join between pillar trims and headlining, then tucked under rubber door seal overlap with headlining to plug into the front (main) unit which will feed along the drivers side headliningdown the door frame and in to the front fuse box

    Just be aware that if you run the power cable along the top pillar where the doorframe meets the front window then you will impede the side airbag, which is not good.

    Thanks for the head-up.

    How far up the A-pillar is the side air bag? Does the A-pillar unclip quite easily (with battery disconnected) to tuck wiring behind the airbag module?

    @LukeHawk I have parking sensors so I can't tell you. I suppose it'll work only when you select reverse.
    @monkeyhanger you can pull the wire behind the airbag. On tailgate there are only 2 screws and metal clips. Check my video from that link.

    Hi @DJAlix, please can you describe the configuration changes you did? I have the camera retrofitted and having the CarPlay issue as well. May thanks, Petr

    I have front and rear factory fitted sensors, unfortunately I still have the CarPlay issue.
