This requires safely evacuating the LPG tank, removing the multi-valve assembly, draining the old fluid, and refilling it with the exact volume of factory-specified Vialle fluid. Fuel Rail Flushing

When troubleshooting performance issues, technicians should follow the manual’s structured diagnosis tree: Potential Root Cause Diagnostic Step Incomplete purging or vapor pockets in the fuel rail.

While official Vialle documentation is primarily distributed through authorised partners and installers, several resources are available to the public: lpi+vialle+technical+manual

: The system performs an electrical self-test; the dashboard LED blinks green.

Use a specialized solvent or isopropyl alcohol to flush out gummy deposits.

Apply a thin layer of LPG-compatible lubricant to the new injector O-rings. The proprietary (v3

stands for Liquid Phase Injection . Unlike traditional vapour phase LPG systems (which convert liquid LPG to vapour before injecting it into the intake manifold), LPI systems inject LPG directly as a high-pressure liquid into the intake ports or, in some advanced cases, directly into the combustion chamber.

Steps for checking injector functionality using dedicated diagnostic software. Use a specialized solvent or isopropyl alcohol to

| Error Code (Manual Ref) | Meaning | Fix (From Manual) | | :--- | :--- | :--- | | | "Pressure build-up timeout" | Replace LPG filter (Vialle P/N 80-00-0015). Bleed air using manual priming routine. | | Err 27 | "Injector rail temp >95°C" | LPG is too hot. Check cooling loop; ensure engine coolant flows through the vaporizer (even LPI has a small heat exchanger). | | Err 44 | "CAN bus heartbeat lost" | Verify wiring between Vialle ECU and petrol ECU. Manual specifies pin 6 (CAN-H) and 14 (CAN-L) at OBD port. | | No comms | PC cannot connect | Loopback test: short pin 2 & 3 on serial cable. Timing: Manual requires 9600 baud, 8N1. |

The pump increases tank pressure by approximately 3 to 5 bar. This ensures the LPG remains purely liquid throughout the supply lines, preventing premature vaporization.
