The best way to sort thgis is to refer to the wiring diagram. There is a liittle panel with a row of diodes on it behind the warning light panel. Simply pull the panel (you have to remove the steering wheel and the instrument nacelle to get to it), sit in the car with all the doors closed, and then go along the row of diodes until you find the one that is trigguring the service light. It could be anything from low fuel, to brake fluid, to door or bonnet open, etc. Once you find which diode if getting the signal, refer to the wiring diagram to see which sender it connects to.
I live in New Zealand, and I am a full member because I find access to information and experience invaluable. We have less than 10 GTAs in New Zealand, so having access to a club like RAOC is worth its weight in gold!
