Audi B8 can bus under beige plug vs gateway 15 can-h 5 can-l
Any one knows the difference between signals carried through can-bus connector under beige plug next to front fuses and gateway 15 can-h 5 can-l??

From beige plug can bus connector I can get steering wheel angle but no camera sensor strength aka radar to display when reversing on the monitor. I have a graphical parking sensor control unit with 8 sensors. (advanced PDC). I plugged to Pin 23 under beige connector (if I remember well) low and high in parallel see pictures.

How would can bus under beige plug differ from gateway 15 can-h 5 can-l?? Are they the same? Conecting Can cables from camera interface to gateway 5 and 15 is it the same as my current connection which is under beige plug Can bus connector??

Any ideas??? Trying to see if I can get radar to display on my screen when reversing.

Graphical parking radar displays when camera interface is disconnected so it is enabled.

RE: Audi B8 can bus under beige plug vs gateway 15 can-h 5 can-l
Thread bump.
Can I tap, my existing camera to canbus connection, to gateway respective can-h/l cables (5L 15H), in order to get radar graphics overlay to display? Or do I achieve nothing by doing this dual connection.

Note:
If I do this for safety I will disconnect the camera canbus connection just to see if radar displays, or if I receive just steering angle again (dynamic guidelines)

I will check tomorrow if gateway 5 and 15 pins exist.

Any ideas?

Maybe it is a camera firmware issue.

RE: Audi B8 can bus under beige plug vs gateway 15 can-h 5 can-l
probably there is a difference in signals carried out by canbus and gateway. I will try two solutions
1. disconnect from can bus brown plug and connect to can-h can-l on the gateway.
2. reverse the gateway cables from camera interface connector to test if any different

If that fails I will try a new interface camera which was sent as a testing sample.

Camera inteterface under testing is RS-1103.
Car tested: Q5 8R auto
Advanced pdc front rear 8 sensors with graphical radar support.
Concert Radio

Dynamic lines working
Parking sensors are less sensitive after camera installation (if cam interface is removed sensors senisitivity is improved)
Reverse can signal works really fast.
Camera image is perfect
image cannot be calibrated
gateway does not recognise interface

Who knows how to change gateway of Audi B8 parameter for camera graphical distance radar activity from Audi Q5 to Audi Q5 facelift????

Can this be done with a VCP parameter ?, Can it be done with odis-e? Can I flash gateway firmware from B8 to B8.5??? (8T to 8R?) Or do I have to change gateway hardware from B8 to B8. 5 in order to enable radar distance???

Note camera interface firmware radar activity supports only Q5 B8.5 which is different than B8.

You need a gateway with extended can, also if you flash your gateway it not work, because need component inside the gateway

A friend who has same issue with the same camera interface, same B8 car said that he has an extended can. So I am not sure that extended can will work. I doubt that camera uses extended can, since my graphical parking distance (APS+) worked without extended can. can you please justify this??? You mean to purchase a gateway from facelift with extended can or from pre-facelift??? Do distance graphics activity signal pass from extended can?? Probably my friend did not connect to the extended can bus (17 can-h 7 can-l) but to normal can bus (15 can-h, 5 can-l)

if I flash gateway from 8T0907468 to 8R0907468 will it ask CP removal????? not sure if hardware is the same to flash with this firmware. do you mean they are different in hardware so firmware update will fail??? May we should forget this idea.

If I change gateway I will buy one with extended can, however buying one from facelift B8.5 (8R0907468AD) might be a better idea with better success possibilities on this issue than the 8T0907468AG from prefacelift but I am not sure that it will cause other compatibiliy issues with other control units. Will this facelift gateway wih extended can solve my problem???


What component are you referring to??? Even with audi camera, or other reputable camera retrofits (kufatec), extended gateway is not required.

I do have a new type of camera interface to test made by different manufacturer (looks similar to audi camera) but will need 2-3 hours to install. (remove glove box, remove screen. remove hvac)

Tomorrow I will try to connect to a different canbus group as I believe manufacturers are using wrong canbus connection (comfort module is not the correct one). If I fail I will give up.
