Hi I have a Fiat Punto Evo 2010 with 1.4 petrol engine which has the engine light on which seems permanent at present as soon as I clear the code it comes straight back next time the car is started I have tried both keys to vehicle but makes no difference. The car has no Symptoms what so ever, starts Ok and runs / drives Ok. Has anybody experimented a similar fault and have any ideas on the cause. Thanks..
