Hi All

Thought I should write quick note about a nagging problem (now resolved)that went on for a few months!

Problem: Occasional auto change to petrol, with beeps etc when LPG tank notanywhere near empty


Solution 1 Go to authorised dealer - plug in to software check and fine tune- No issue found

Solution 2 - LPG man suggested sometimes coolant temp sensor go intermittent- change sensor - no improvement

This turned out also to be a wrong diagnosis as once the LPG receives the50C temp from the coolant sensor it does not check again till next restart

Solution 3 - Change LPG pressure and temp sensor in LPG injector rail - noimprovement

Solution 4 - LPG man said sometimes tank solenoid intermittent - can disableby removing coil, turn off manual valve, remove valve cover (small gas escape)remove solenoid "slug", replace cover, turn back on

This at first seemed to fix - no problem for a month or so until heading SYD- ADL for Xmas problem reappeared under cruise control on hills

Turned of valve and removed solenoid etc, again left slug out - OK for nexttank then again same problem

By now I was suspicious of the Excess Flow limit valve in the tank, soarranged a new one in advance for Adelaide (We arrived their Xmas evelunchtime) and was able to pick one up and have an empty LPG tank

It seems that the small gas escape when removing solenoid slug allows the XsFlow valve to reset completely, thus delaying onset of next trigger of the old oversensitiveunit.

Solution 5 Changed the valve in ADL

Drove back SYD and around SYD since then (7 or 8) tanks without further problems
