Does the fault reappear if you clear the code then run only on petrol? If so, then it's not likely to be anything to do with your Prins system.
However - Vauxhall coil packs are well known for failing after a while. When was the coil pack last replaced? If you've done 75,000 miles and not replaced it then I would certainly do that. They're not that expensive and very easy to replace yourself.
thanks Rich. The car has done 55k miles and I have replaced nothing except spark plugs and the usual service items. Yes- the management light reappears irrespective of whether I am on petrol or LPG. If I take it to the Vauxhall dealer for a basic diagnostic check would that give any more info than my iCarsoft i902 OBD fault code reader as to the source of the problem? I phoned them today and they were very woolly as to what the initial £75 check could me - all they said was that they wouldnt trust a 3rd party source - ie my fault code reader. When it comers to trust - I dont trust them from past bitter experience lol of work being done that wasnt necessary.
