Ok that makes sense, there is no hole in the trim over the rear wheels so it will probably located over it, need to jet wash some mud before and try to remove the trim. Thanks

Hallo, yes but both the indicated howto and my own inspection beneath the C and D pillars do not show any drain pipe. I know for sure that Tiguan has rear pipes and the sunroof should be exactly the same. "Tailgate" is the trunk door, right? Cannot see any exits there as those ones in the front doors.Thanks.

So there is no rear drain pipes ? Only the 2 in front? tx

Hallo where can I find the exit of the rear drain pipe of the panoramic roof? Thanks

It is an understandable question .. the first and less understandable answer is "because I can", but to be more pragmatic, let's say I live in place with a very mild and sunny climate (Tenerife) and want to have a single action to lower a bit the front windows and open up the panoramic roof when I get into the city from the highway (I know.. I know..). Also take into consideration that I may use the steering wheel buttons (which I have already decoded) to do that action instead of the radio. Thing is that writing and Android app (Android Auto compatible as well) that will somehow talk to the SPI port of the RaspberryPi (where the canbus controller is connected) may be a long shot, while I have plenty of unused buttons on the steering wheel.

Some happy updates, I got some working codes you can have a look at them in this github project: https://github.com/simonemarin/vag-canbus, I will update that page with new findings. About the windows, there are 2 IDs , one is for the command (same as pushing the buttons) the other one is for getting the current position and the direction of the movement, so it is technically possible to move the windows to a given position. No luck with the panoramic roof though, I think that the knob is connected directly to the local controller and is not communicating with the canbus, but there shi=ould be a way to raise at least since it is possible to raise ti with the remote/key.

Hallo I need to replace the sun shade of the panoramic roof, I already have a guide to work on the roof so I am covered there, but I fear the most difficult part is getting to it. As far as I know I need to lower the back portion of the roof trim, thus I need to remove the 2 C pillars, the center lock and the center seat belt. Any guide helping me out there? tx Simone

Bingo! I managed to wire into the connector without having to cut anything, just plugged a couple of dupont male headers in. I can read the data unfortunately I was not able to send any meaningful data, I can read windows open/close, door lock, etc. but cannot control it with the same messages. I am not sure if somehow the gateway is blocking my signal or if there is a specific sequence of data that must be sent. I will keep you posted.

mmm that is actually a good idea, I know I can get some of that data in the Infotainment bus (for example the fan speed, probably because the original radio could had that data) but that is read only, I guess the gateway is doing some filter magic to avoid any kind of control from the Info bus. Thank you, I ll let you know.

For example I am pretty sure I can get to the Convenience bus from above the glass storage compartment but that is difficult then to wire all the way to the head unit, so something closer to the dash/head unit would be a good choice.

Hallo, I have built a head unit with a touch screen and a RaspberryPi, I was able to hack into the entertainment CANBUS so I can get the steering wheel buttons data, so far so good, but now I would like to be able to control the panoramic roof and windows, eventually this is not possible on that CANBUS and neither it is possible (or easy) from the OBDII port CANBUS. So next step would be to tap into another bus, are the schematics available anywhere? Thanks

Title says all, I have modified the Yeti as a small camper and built my own audio unit hacking into the canbus. Cheers.
