I am slightly more optimistic about the UK supply. There have been production problems and demand has exceeded expectations. PSA have just announced a couple of weeks ago that they are about to add a fourth shift at the Sevel Nord factory and another production line is planned for Russia.
Back on topic I have been looking at the Peugeot Expert and Citroen Dispatch vans online and 95% of those have the basic instruments and steering wheel, but a small number have the upgraded instrument set with the better steering wheel with the buttons, but I can't quite pin down what triggers that from the options list. It is not the centre screen as nearly all vehicles have those now. It could be something such as the Active cruise with autobrake option that might specifically need the LCD display or something similar that determines what is fitted.
When I pick up my new car I will ask the dealer if they know.
