Thanks for all that information
Hope these are my final questions
In my case, apart from previous problems that have not occured in months (IS rebooting itself, heating controls locking up and Media / Radio not fully loading) the one that still persists is the central unlocking only working when approached from the rear. If VW don't offer it, do you think I have a case to get the software update?
Is the above 1896 the same as the much publicised hardware / software update announced recently by VW?
Separately, again in my case and for many other the driving errors - parking sensors etc that are still appearing - will these ever be corrected or do I / we have to put up with them forever! (have the car 16 months at this stage)
