I have a 2017 Autotrail 15k miles, fitted with a 2.3 Ducato diesel engine.

I get the "engine check" warning light coming on.

The garage in my area has checked it out with their laptop and it shows lambda sensor problem.

They have replaced the sensor twice with two new ones but the light still comes on.

There is no loss of power or drop in fuel consumption.

The auto electrician has checked out the wiring and says it checks out ok.

Any thoughts or suggestions please.

The most common cause of the general failure warning light is an incorrect starting procedure apparently. Happened recently on my 20 plate 2.3 Ducato.  If you do not wait for all the dashboard warning lights to extinguish you run the risk of a low voltage start causing the light to show. Common on vehicles not used regularly. Confirmed by my Fiat dealer. Not happened since I adopted the new more patient start up. This warning light does not record as a fault code when read by the OBD also confirmed by Fiat.
