I tried the ignition switching suggested by Glenda just out of curiosity and instead of the service reset on my Kangoo 1.9 turbo diesel I got the following :-
ALL the lights came up on the display, even ones not valid on my car.
The mileage was replaced by "CAL A"
A musical tone played and all the gauges went through a sequence of :- zero, 25%, 50%, 75%, 100% of full deflection.
This kept on until I switched the ignition off, subsequent to this the problems I've had with the immobiliser SEEM to have gone!!!
