Hi Exonian. My basic spec also has no red edges on the seat belts or the ambient lighting. Not sure why as it's still a GTI so thought it would have a least came with the red strip in the door. Still love the car though. 
It's a strange omission and VW's reasoning of the bucket seats option makes siting the ambient lighting controller impossible sounds a bit suspect.
As for the red edged belts, it seems to be a lottery
Exonian, the red stitching comes with the bucket seats. No ambient lighting on any UK CLubsports. Shame as I miss the red strip lights in the door.
The coloured door strips are the coolest feature of the GTI & R
I don't miss them as much as I thought I would as the LED light above the mirror acts as a spotlight on the seat pattern when the door opens and the rest of the interior is in darkness but I did really like having the coloured strips.
The red stitching also comes with the standard sport seats.
Not on all UK cars it seems
Has anyone tried taking the door card off to see if it was there? VW have been known to leave things in and just not connecting them. My CC's all had heated rear seats with all the wiring and all I had to do was buy the switches and plug in the wiring.
According to a German forum it seems the honeycomb 40 door panels don't have the LED insert.
What adds weight to that is there are no holes for the white LEDs in the door opener aperture.
It's less things to go wrong I guess!
