Replying to my own post incase anyone else needs it, the brown wire is an earth. All up and running, working fine and thanks to all who helped me. I saved a bunch of cash which is always nice.

Hi Eddie, very kind of you to assist, the Bluetooth unit is a 5K0035730D is it any good? The green connector went in OK and I soldered the can wires into the twisted pair coming out of the quad connector, that went OK. I picked up a permanent live from the radio supply, again all good. My only unknown now is the brown wire, I have been told its an earth, but also after second power, can you advise on that one please? Thanks for your help.

Hi folks, I have recently upgraded from a Bolero to a columbus unit in my 2011 Octavia Estate Greenline. I have fitted the unit and a new Bluetooth controller, I'm using loom of part number 1K8035730D. This loom has a green block which connects directly into the head unit via the original connection block. There's also a microphone cable that runs up to a position in the interior light switch unit. I am left with a twisted pair (can + & can -), a red and a brown wire. Can anyone help me with where to solder in the twisted pair and the two spare wires which I know are power related, but I need to verify exactly what they are. Thanks for your help folks.

So the windows both operate after I disconnect the battery and leave it for 30 mins or so. They also operate on the door key for open/close. So a broken wire is pretty much ruled out. I think it's starting to focus in on the regulator controller??

I've looked in the door gap and under the dash

Both front windows are intermittently working, fuses OK, cant find any loose or broken wires. Any history with this?
