Hey all, I was driving my 07 plate impreza hawkeye sport today, when the engine light came on and has stayed on, the car is still running normally but, I'm worried that it may be something serious, as it's my only car at and Im not able to get it to a garage for at least a week or two, if not longer, is there any way of getting the codes or/and reading & clearing them without a obd reader or taking it in? Cheers Terry
