I need to turn off a permanently lit battery warning light on a new style Corsa. It is my wife's car, and my daughter needs to take her test in it tomorrow. My Wife says it has been checked during servicing but not fixed - there is no actual battery problem known. Wife says the light has been on ever since she had the car. Daughter cannot take the test if a warning light is showing, apparently. Anyone know if this can be one as a matter of urgency. Just to add, I am pretty mechanically inept.
