hmm, gona tell my dealer to reset ECU but batt was not flat
I'm not sure if the Roadster is the same as the Aero but there is a kill switch inside the engine compartment, which you can press to disconnect the power to the car/ECU.
Leaving it off for 5-minutes resets the ECU - usually you can then push the switch back in, start the car and everything is (fingers crossed!) fine.
