After a year got it sorted. The BCM module under the steering wheel was changed and connected it to vcds. Done a key adaption and now is working fine. Before this I did notice a few wires sliced in the driver door loom bit that didn't fix the problem. Was the BCM in the end.
Hi
Sorry about the late reply. Unfortunately couldn't get it diagnosed as the guy had some family emergency. I will update the thread when I have the readings. Might be this weekend
Thanks

Thanks for your help. Yes please can you send screenshots when you get a chance and I can compare mine. Is there anyone close to Birmingham that has VCDS that I can visit to get a Autoscan done?

The 2 pics are taken before the change. We used the same pictures to enter the original values back. I'm not sure if an Autoscan was carried out initially.

I'm not sure about the coding sections. I think my friend was following a step by step guide when he done it. But he has assured me many times that the only 2 values he changed was the 2 pics he took. When I paid for the coding to be changed back these 2 values were only changed.

The photo shows the VCDS we used on the initial retrofit. When we changed the values back to how they were I had to pay someone to come out and do it as my mate was unavailable. I have contacted the person I paid and he has said he is using the latest version with an original RossTech cable...
We tried this. The problem isn't with the key itself. The VCDS can see the key and also acknowledges the key press. The issue is we can't save the new value because it can't communicate to the module. We checked the fuses in the engine bay and the side of drivers door bit all were fine.

I can only assume it's the control module itself. However I have no idea where it is and if it is even replaceable. I have only one key so I can't also do the self key coding if that would help the problem.

The coding was reverted back to what it was before the retrofit. He assured me that only 2 values were changed under section 16 and 17.
The original values were screenshot before changing and this was used to revert back.

Hi
I have a 2010 A3 2.0TDI 140 Sportsback S Line. After having a friend retrofitting cruise control to the car my central locking via the key fob stopped working. The central locking works fine using the drivers door lock and the drivers door interior lock switch. The key shows the red LED when...
