Default S8 D2 OMVL LPG Question

So the car has just been fully serviced, MOT'd and a complete and full cambelt change done.

Though today I have noticed a strange problem with the LPG (was working perfectly).



The system when running on LPG should be just on the G (Gas ON) with the Petrol pump out. When warming up the Petrol Pump stays on and the Orange G flashes.

Now all I ever get is the Red Pump on and Orange G flashing, it never flicks onto LPG even when warm. At idle I have seen it change to LPG only to go back to petrol as soon as any revs are introduced.

Now this may be the Thermostat, Filter or Solenoid at fault so I have ordered the cable to plug in and have a chat with it. But I wanted to ask the question at least in case one of you fine ladies and gents have had similar problems?

The system has been filled up with LPG in case that was it, plus if I cannot resolve it will go to the local LPG specialist for a service and fix.

I have done the normal forum searches and OMVL manual reviews but not come to anything that conclusive.

Car drives beautifully I should add

Finally anybody know the normal home for the LPG ECU?
