Default Lpg help?

Anyone on here know LPG? ECU keeps going off and requires resetting, can't seem to find anything that would cause it? Any ideas? Tia

I've had LPG on my car for almost seven years and only ever had one problem with it, and that was within the first six months. The car ran fine, but after about two miles of running on LPG, it would give a loud beep and switch back to petrol. The problem was due to a coil pack going bad, and the system detected it.

Curious about the image you attached. Is that software allowing you to access the LPG controller?

Mine started misfiring so had leads changed which solved the issue, till recently when misfiring came back, new plugs solved that.

It doesn't allow it unless I press reset at which point it switches to gas and all is good.

2 mornings on my way to work it was faultless, on way home it wouldn't stay on for the life of it. Got new reducer temp sensor coming as one error code that was coming up was relating to reducer temp being low, but I would expect it to just switch to unleaded not go completely dead.

I had LPG on a Commodore many many years ago. Very basic analogue system, so i can't help with the ECU side of things.
However one thing I do remember is that the recommendation was to run a 1 or 2 heat range cooler plug to promote better combustion with a cooler denser charge in the cylinder.

- has a louder more obnoxious exhaust than the S8, sounds great! Love this thing - Q7 was double the price, and certainly not double the car!
