ACC radar is at the front just under the bonnet release.
Check the connection.
Otherwise see VW

I got this message previously. It turned out that it was dirt on the front camera.

I hope this helps

To remove the radar module you need to take out the front VW badge, then the radar module unclips and comes forward.
If it's under warranty though I'd be inclined to just take it in to VW.

Yes, it's under warranty, so will take it to dealership

It's trying to talk to another module.
A V2 vcds cable will be able to give a more detailed output. Do you have faults against any other modules?

It had few but i cleared all of them. Then tried to do full scan and then stopped halfway through 14/25, as it was taking time.
Will scan now again to see
