Hi All, just a quick update: New battery fitted and exactly the same problem.
During the drive to get the new battery (charged the old one up fully before setting off), a journey of about 10 miles all in, the warning light was off for about half this time?
When the light went off I stopped and checked the voltage with the engine running and was getting about 14.5v, when the warning light came back on later I stopped again to check the voltage again with the engine running and it was 12.5v
So it is looking to me like and intermittent Alternator fault or a bad connection somewhere, has anyone ever had to remove their alternator?, it does not look like an easy job, at the moment I'm guessing that I will need to remove radiator to get to it.

Hi All, just a quick update: After trying all the suggestions I gave up and gave it to my local garage, they could not find anything faulty so replaced the alternator and now all is OK, also replaced the belt while we were in there just in case. They went in through the drivers side wheel arch, removed the intercooler hose, unbolted and moved out the way the AC compressor and also had to remove the engine mounts so as to move the engine a little to the side to make enough room to actually get the old alternator out and the new one in.
£360 all in (£160 Parts and £ 200 Labour) which I did not think was too bad.

All good now, it's the first problem the car has had since new (10 years and 103,000 miles)
