I rarely use the car on a long run but did so last week, the engine warning light came on but nothing obvious. The following morning on switch on the light went out, a week later it came on again. I plugged my OBD reader in and it showed 3 codes but N/A so not sure why as N/A on searching google means manufacturers codes not compatible. The only thing i find on the car, since buying it, is the fan constantly on. Its a 2010 Corsa D Anyone else had this?
