Just reset my inSP light on the astra today by pressing and holding the reset for the odometer while turning on the ignition worked fine all reset. BUT just wondering? while my ignition is on and i hold the reset on the odometer for 2 or 3 seconds what is the milege that shows up? mines done 58000 and something but when i hold the button in it says 24000 and something? don`t know if anyone else has tried this?
