Good morning,

This car comes with engine light on with P0088 flute pressure present, and petrol/LPG switch fixed on petrol even if switching to LPG. Replaced clogged LPG filter, cleared fault, but if I try to switch to LPG, as well as not lighting up the LPG led, remaining fixed on petrol, the engine light comes on with the same error.

With Logic, actuator testing of solenoid valves would not be possible. I assume that the circuit must be pressurised. I would like to ask if there could be any tips.

Greetings.

Stefano Vallini
