Hi,
Which engine?
The correct way to do it is to use
Multiecuscan (
MES)
www.multiecuscan.net or similar.
With most Fiat Petrol models it will go off on it's own eventually. On Diesel engine models with a DPF it will eventually go into lim mode and may damage the DPF.
There is a "pedal pushing" method that may work, use it at your own risk
1-turn on the ignition key,
2-press the accelerator pedal and hold it,
3-press the brake pedal 7 times without releasing the accelerator pedal,
4-keep pressing the accelerator pedal for 60sec.
5-Release the accelerator 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.
