My car is a MY00, and its a bit wierd this problem, not sure if it is by design or not

Basically my door open warning light has been on for the last day or two, even when the car is locked & alarmed

So had a fiddle about with switches etc today, to no avail

Then I realised I had turned off the interior courtesy light (due to working on the car for a while with the doors open)

So I turned it back on, to come on when the door opens, and Lo & Behold the door open warning light went off !!!!

Strange, any one else get this?
