One of our newer members, b4kyk, has asked me to help coding his 06 Octavia as he is fitting a Columbus HU instead of the Audience.

Whilst I have the full genuine HEX-CAN USB VCDS I have only used it to code DRLs, Cornering Fogs, MPG corrections etc.

b4yky has purchased a 1Z0035680A - Head Unit and a 7N0907530C - Gateway

 

Before I start could somebody please confirm this procedure?

1) Scan current modules on car and keep a copy of all the settings especially the CAN Gateway

2) Remove existing CAN Gateway and replace with 7N0907530.

3) Code new Gateway with same settings as old one. Can I just enter the original coding (mine is six digits long) or do I have to go through each screen and check the correct boxes?

4) Make sure car starts and runs with no fault codes.

5) Remove Audience HU and replace with Columbus. I assume that he will need to install a GPS aerial but an 06 Octavia will not have the diversity aerials that the Columbus expects therefore we need to use the Antenna 2 socket but we will get an 'Open Circuit' fault when scanned with VCDS which is nothing to worry about.

6) This is where I need some help as I am unsure whether the Columbus will then work correctly or whether it needs a code entering somewhere.

3) Take screenshots of the current configuration, so you know what the coding actually refers to. From everything I've seen on here, no-one has ever recommended a "copy and paste" when changing gateways. You can then compare before and after if anything is adrift.

 

5) You can get a splitter which will let you connect 1 aerial to 2 sockets. If you're only going to use 1 use the inner one of the two, that does AM and FM, the other does FM only. Plenty of room in the dash for the GPS unit too

 

6) Yes, you will need the 4-digit code. Enter that and rock'n'roll!

Thanks for the reply.

I have scanned my car and see what you mean about the check boxes so I wil be very careful to record all of the existing settings.
