Just to update on the problem.

Tried all the previous suggestions on the site and I finally used the suggestion of disconnecting the battery for 3 minutes.You guessed it.Everything back to normal.Rooftop switch and Rollbar switch no longer lit permanently.Again thanks to all the advice supplied by members.I was told the earliest the Main Dealer could look at the problem was next Wednesday week and I was probably looking at big bucks to fix the problem.

BTW I have Trisco Scantools hand held diagnostics unit.No seperate OBD socket in the cabin all built into the 39 pin plug in the engine bay.Tried to read the fault codes for RB and RST.Message "err reading codes" came but it allowed me to clear codes.That still did not solve the problem.Anyone familiar with the Trisco diagnostic unit.I would like to learn more on its use as the Taiwanese "manual" it came with is crap.
