Just seen this over at Motortalk.de, and thought I'd post up here.
Here is a supposed list of changes coming for post build week 22/16.
Elimination of AM Radio band (all models)
Discontinuation of colour Sunset Red (all models) - not sure if we got this in the UK ?
Elimination of Blue brake calipers (guess that is for the GTE) ?
Discontinuation of colour Crypto Steel Grey ( I hope that's not Carbon Steel Grey in UK talk) ?
Elimination of the lock facility for the glovebox.
Elimination 18" Serron Alloy wheel
Elimination driving profile selection and DCC for 81kW TDI
All in all doesn't seem too major (unless anyone knows otherwise), so looks like VW is either saving up the major changes for the facelift rumored to be coming late 2016, or for the new MK8 ?
Also, now "apparently" confirmed by VW that in November / December, the MIB III with Gesture control and home screen, larger display in the DP Pro will surface, as can be seen on the below youtube video
