Rear view camera retrofit doesn’t work

[henkkeumus]

I contacted with seller he send those photos....i read somewhere else that maybe CAN-high & CAN -low wires have to be reversed thats why 6C module cant be registered... I'll try it later on....

red: power,
black: ground,
yellow: video+
green and white canbus hi/low

CAN + = pin6
CAN - = pin 12

Well that is has 6pins is a good thing tough.. if you cant enter the 6C module then its a communication error (if you sure that it has proper 12V and GND). This comed down to your canbus connection. Are you able to do any continuity test on the wires?

From which side shall i try ? From the trunk handle or front dvd unit ?

 

[maniasg]

CAN + = pin6
CAN - = pin 12

Ok i will check behind dvd if are correct and i will tell you

 

[henkkeumus]

Ok i will check behind dvd if are correct and i will tell you

Orange/Brown = CAN Low = PIN 12
Orange/Purple = Can High = PIN 6

If they are reversed you can do the following;

Pry the lip holding the grey connectorblock on it's place UP. When it's up push the connectorblock to the backside of the quadlock. This will get it out.

Then to get the pins out pry the sides loose and open. When they are open gently push the pin in the connectorblock releasing the "spring" that is keeping the pin in place.

So i know from the seller that i have:
red: power,
black: ground,
yellow: video+
green canbus hi
white canbus low

I'll check if pins are correct as you said ...thanks again for you time and for you help....i will inform you

 

[maniasg]

So I'm back ...i check everything today canbus hi low , 12v , ground cable .... everything are correct and work properly....but camera reacts same sh***t ....its coding issue but what???

Well, if that is all correct and the 6C module is not reacting or working then you can safely say that your camera is not working 100%. I would ask for either a refund or replacement camera.

If you are going for a refund, I would recommend this one, I installed this myself too, pretty easy and I have even made a write-up in proper English instead of a Chinese translated manual . You can PM me if you need it.

Its says for A3 ? Its suitable for me? I cant find how to send you pm ...if possible send me i would like to ask you some things

Okay, so after doing some tests I’ve found something interesting.

When I put the car into reverse and then reset the MMI, while the MMI is booting up it shows the reverse image for a few seconds and then disappear once it boots up.

That’s why I’m 200% sure the problem is in 5F.

Did you ever sort this mate . As Iv got the same problem? Thanks

 

[Mike migk]

Maniasg or tbishop93 hello mates.
did anyone of you make that **** camera works?

 

[Juananq2]

Where did you install the CAN connections?

off the top of my head no but if you look at the long coding you just need to activate the bit / select the drop down for reversing camera.

Hi DJAlix, I've installed a Sinosmart reverse camera (same as Maniasg, below in the forum) in my q2 2018, and I have the same problem than Fraysa and Alejandro Montemayor, the camera works until mmi initiates, then dissapears. I've tried the coding they say with vagcom (vcds 23.1 version), however I get problems to communicate with 6c, I get the message: controller doesn't respond) plus getting into 5F (communication error, after a few of them it says too many errors and back to installed modules). Do you have any idea what's wrong, maybe my vagcom is not working well, the camera wiring...? It'd be nice if you could give me some idea what's going on. Thanks in advance

 

[DJAlix]

short answer...

No such thing as VAG com, the legal name (of genuine software) is VCDS. I would need to see the car to workout what's going on, or at the minimum a full and unedited VCDS scan.

It looks like an issue with your VCDS connection if you can't even connect to 5F!....

Sorry not too familiarized with terminology, I meant the cable to use with VCDS (Vag-Com Diagnostic System Here's the log file of the scan (I changed to 20.4.1 software to see if there was any change but I gor even more fault messages :-( . Thanks

lol latest VCDS version is 23.11, why are you using an old version ?

Use genuine not copies.

I used first 23.11, I explained in the post why I changed. It's not a bad idea to read the full post before answering an "lolling". Moreover my car is 2018 so 20.1 should be ok to diagnose it. Thanks anyway

Never had an issue using the latest VCDS on an older car lol.

Wow, what happened to this car?.... so many errors in the modules, never seen so many before, 5F doesn't even try showing the errors as there are so many. As a first step I would recommend clearing all errors and seeing which ones come back.

As for 6C, no communication, so either your power lines or CAN-bus lines are not connected properly.

 

[DJAlix]

Update to latest version (free if you have a genuine interface and no reason not to run it), start the engine and perform and auto scan. When finished save the results, clear all DTC, cycle the ignition, wait a couple of mins ans then perform another auto scan. This will make sure you don’t have any histories errors logged.

On the face of it you have a lot going on on your vehicle. You need to check your power and earth for the 6C. If they are ok then you need to revisit the CAN connections, assuming the camera you are trying to retrofit has them.

Hi again and thanks for the tips. I decide to remove the "bridge/bypass" bunch of cables of the retrofit camera and tried new vcds scan, and as you can see in the log file, most of the communication problem with the modules seem to be caused by it, as I could get into all of them. The new problem I face now is that the module 5F it's not correctly coded and I've los the functionality of the audi smartphone interface (bluetooth, android auto...), so could anyone let me know how could I get the correct coding for this module? (not having to go to Audi dealer obviously). There's also a problem in module 17, I don't know if it also interfere with the mmi problem.

What you have there is a reversing camera low. Return your coding changes (in every module) to stock / what they originally where, then all you need to do is tick reverse camera low in 5F long coding.

Hate these cameras.

Thanks again, but the problem is that, I don't have the original code for that module 5F, since before I couldn't communicate with it and all the logs files I saved are without info of that module, any idea how can I get this code.
One more thing, any suggestion for another camera model? since I can see you are not very fond of that model. Thanks and regards

Genuine Camera

What you have is a “dumb camera”. It’s power, ground, reverse signal and video only, no CAN. As it has no CAN or module you cannot code it. All you need to do is tell the 5F that you have a reversing camera low connected, which is done via byte 19 in long coding.

Coding changes you might have made already would be:

10 - park assist, byte 2.
19 - can gateway, installation list 6c.
5F - Infotainment, adaptations VPS active and VPS message bus infotainment.

If using VCDS then look at your logs in order to see what was done and when. If you were using OBD11, then may the force be with you.

Luckily I have vcds and managed to restore the infotainment system changing codes to stock. But when activated bit 4 (reversing cameralow) in byte 19, the original problem I had persist, i.e., I see the rear camera image in the monitor when I put reverse gear and restart infotainment system, but as soon as the system starts, the image dissapears, somehow it superseeds/blocks the camera signal. Any clue?

 

[DJAlix]

You need to visit / use the services of a specialist in order to conduct local testing etc. Personaly I would remove the camera you have and place it in the trash, source a genuine camera, install, code and then enjoy a fully documented, working and stress free retrofit.

I'd advise not bothering with any AliExpress cameras.

I fitted one, worked first time, I was really impressed, only to notice the picture is wonky.
