Well I think this may be the final post to this thread as the problem has now been solved. Before I describe the solution I also discovered the sunroof did not work either.
As prompted by a number of forum members I finally went looking for an auto electrician (not the dealer who told me it was probably an FRM) to investigate the problem.
Pulled up in the fore court and made the mistake of turning the engine off because every time I turned the ignition on the alarm would start and run for about 5 to 10 minutes. The auto electrician came out with a set of ear plugs on. Plugged the right kind of scanner into the OBD port and then went to the fuse box in the glove box. In about 2 minutes had found a 5 amp fuse that had blown (I will try to find out which one when I go back on Thursday). Then just as suddenly as they appeared all the faults disappeared.
At the risk of having the scorn of forum members heaped upon me I will suggest that this could be described as a design fault when one 5 amp fuse could totally disable so many quite significant functions. If I had thought that this was likely I would have been more diligent in my examination of the fuses (I did check all the fuses in the back).
So my advice for future readers of this thread: check your fuses (all of them).
I would like to thank all of the members for their suggestions many of which contributed to my finding the eventual solution and prevented me pursuing wild geese (eg footwell modules).
PS Happy to receive suggestions as to a good make/model OBD scanner but I notice that other threads have addressed this issue.
Thanks again.
