Romano lpg help

hi i have a rr p38 with a romano lpg sequential injection system .
when i switch to lpg with a full tank of gas .it switches over and then all the lights swith no and the audible warning sounds .and it switches back to petrol

do the lights flash and is the tone continuous or an intermittent beeping?

also, why manually change over? the system is set to auto switch when parameters are met.

i had a simliar fault on the same system, i discconected the battery and all was well

not working for me

Mine does this occasionally. Can be very frustrating. Sometimes I can just shut the ignition off and it's ok. Other times it'll keep on doing it. It sounds every couple of seconds and flashes.

Mine is doing just that..The LPG experts here say they dont have the software to clear the computer...They say it isnt broken,just blocked. In Italy Friday so hope I can sort it there.
Doing a 4000K trip and it makes a massive difference to costs ;-(

Hi what r they saying is blocked?

The computer .

I have just been told that this means that there is a electrical fault .this is likely to be a senser .and most likely the pressure boost sensor. Can anyone tell me where this is and how to test it please

Depends on the install and who did it as LPG components can be placed in various locations and where it would fit!

Best course of action is to gooooooogle and look for images of what it would look like and then see if you can spot it in your engine bay!

Never heard of one before called that, but my BMWs OMVL (I believe AEB, Romano and OMVL can share common components depending on install) setup has a LPG Pressure sensor and a Manifold Pressure sensor fitted and looks like this....



One input is for the Pressure sensor and the other measures manifold Vacuum...

If you take the pressure pipe off the sensor with the engine stopped there should be gas pressure there. If not one of the gas valves is not opening or you have a blockage.
You can also get the LPG ECU software from Ebay -

Sounds like the gas pressure sensor to me.

Pressure sensor could make sense, mine only seems to do it when there's less gas in the tank.

hi all well i took it and got it plugged in .it come up with to faults .one was the temp senior. and was tolled that they some times go forty. and when they do some times you can clear this by descenting the battery . but not all ways .and the and the second was that romano do not have a filter .so you have to to strip and clean the solenoid shut off valve.dune this and all good. plugged it in agene and no faults . was told that the temp senior my be ok some times it is just a way of the ecu make a fault so it will shut down . i got a new tep senior but did not fit it .just dun 120m and no problems:hippie::kettlepot:

thanks for all the help

Nice. Easy enough to strip and clean??

Yes it takes about 15 to 20 mins
