Engine warning light on a Fiat 500 with original LPG system.

Model: Fiat 500 500 L - Years 2012-2023
Part: Checks and maintenance

In this video we see what is the reason for the engine warning light coming on in a Fiat 500 with the original Landi Renzo gas system, the one installed by the manufacturer. The symptoms it gives are that, when starting, the car runs on three cylinders, and after a few seconds immediately switches back to running on gasoline. The diagnosis made by a professional tells us that it is a failure to ignite the gas in cylinders 1, 2, and 4. A check was made on the pressure reducer, but it is working fine, so the GPL injectors and the two filters, both the liquid phase and the gas phase, need to be replaced.
