Golf VI R :: Getting Ticking Noise Idle In Cold Weather

In the cold weather I found I had what sounded like ticking noise at idle on the R. It doesn't do it when first started and I didn't remember it in the warmer weather either. My research indicated it could be the DI injectors or the N80 valve. But what got me concerned was that I could hear the ticking inside the cabin, somewhere in the front passenger footwell area. And at times over normal radio volume. This was not the case in any of those other threads on the issue as they noted the sound only outside the car.

So I took the car into the dealer this morning to see what they would say. Had a good tech check out the car and try a few things. Turns out the tech found it was the fuel line underneath the car rattling. He said this was a common issue in the MK V cars and there is a service bulletin out on it, but he had never seen it on a MK VI car.
