Hi , I've just fitted an aftermarket reverse camera , the boot handle type. It came with a wiring harness which plugged into the back of the Columbus Head unit and to the existing harness. Everything work fine except I now have no dab . I've put it on the diagnostic and it says dab open circuit.

Any ideas would be gratefully received

Show the Set of Camera?

This type with can bus , I had to remove quite a lot to get the head unit out as the wires would not let me pull it completely out as they seemed to short

Hi all, I've found this picture online with it saying that this (circled) is the dab Ariel port. I didn't realise that there are so many different fakra connectors. Can any of you tell me which one this is ?

Apparently there are A,B,C,D,E,G,K and Z

I've got no idea,

Do you have any cheap usb chargers plugged in?

My DAB stopped working and it was cheap 12v usb adaptors. Unplugged them and DAB magically started working again.

I have a similar reversing camera in my superb without issue.

The black plug is the DAB. Have you definitely plugged it all back in correctly. I have had issue with the wires being very tight behind headunit with the extra plugs from the camera too. Could be putting pressure on some wires.

Yeah I was thinking that I've accidentally pulled the dab plug out when refitting. So I'll have to strip it all back out to check. I've nothing plugged in anywhere to be honest. So it's the only thing that comes to mind. With mine you have to undo most of the lower dash panel to access the back of the unit because as I've said you cannot pull the unit fully out as the cables seem to short. There's a distinct lack of space behind there .

Cheers

There will be a cable tie that holds the bundle of cables to the dash rail. If you very carefully snip it you will have better access. On my superb you can just get to it above the fuse box but I’m not sure on kodiaq if it’s the same.

Yeah there's one either side ,I cut them both but still wasn't enough to pull all of the way through, I'll have the dash out tomorrow and hopefully see what's happening.

So problem solved, after taking the dash apart I found that the dab plug had not come out but the innards of the plug had come loose more than likely due to pulling at the head unit to remove before finding out that the cables were short and before taking the dash apart to to the job correctly. So I've fixed the plug by fiddling with it and a touch of super glue . Let it set ,put it back together and voila everything works as it should .

Thank you to the members who replied and commented on my post ,any help was appreciated.

Cheers

Great well done. Love it when it’s a nice low cost fix.
