Nigel,
I beleive that Caterham can reflash the dash controller module (PCB mounted behind the dash) to stop the indicators affecting your ability to turn the engine off, there was also a problem with the headlamps being on and in a certain state affecting the switching off on the engine.
It would be interesting to know if they could reflash it to stop a long push when the engine is running, re-engaging the starter, maybe a timer controlled function from initial ignition switch on or crank to stop recranking without an ignition cycle?
Regards
Andrew
