I have just received a response from VW confirming what you have said, that the clutch would not disengage under those circumstances, even with City Emergency Braking.
This is contrary to what our salesman told us when we collected the car, and I am rather concerned that he misinformed us. I think more training may be a good thing.
On a more general subject, we are pleased with the new car but not so happy that this and other things are lacking: the dipping (nearside) wing mirror in reverse doesn't work and neither does aspects of Guide and Inform services, such as Vehicle Health Report and recording of where the car has been parked.
Admittedly, these things are not of any great importance to us, but I think that if VW advertise such things as an inducement for customers to buy their products, they should at lease ensure that they work properly.
I recall that someone on this forum did state that Car Net is a gimmick and I now have to agree with him. Another person said that the NAV addition to the SE model is not worth having and, again, I must agree as using Google Maps on the screen negates any advantage of using the Navigation map, certainly for traffic flow information as the NAV map shows only traffic flow on the major roads, whereas Google Maps adds such information on many more smaller roads as well. If we should buy another Golf, it will certainly be SE and not SE NAV. We live and learn.
