Thanks Alex - I did find a garage that has J OBD scanner system and they told me one of the HV Batteries was 'unusually different' and to contact Hybrid Repair Service on the south coast somewhere - they said nah the difference was negligible and they would come up here (Stilton) and sort things for £1000 - don't appear to have anyone nearer to me who knows about Alphys - the local Toyota Main Dealer in Peterborough have never seen one they tell me....
