just found this and it worked ,,!!! Reset oil light after service... that is very important. And don't skip the oil change either. 1-turn on the ignition key, 2-press the gas pedal and hold it, 3-press the brake pedal 7 times without relesing the gas pedal, 4-keep pressing the gas pedal for 60sec. 5-Release the gas pedal and turn of the ignition key, 6- Wait for 60sec. Then turn on the ignition key and start the engine. Check if the service/oil change light turned off. That's all! The vehicle is Fiat Doblo, works on Linea, Qubo/fiorino also vauxhall combo. 2012 forward...
