This is what tuning developments sent me when I was chatting to them! ECU codes, in the diagnostic port under the bonnet, bridge TE1 and E1 with a paperclip, then put your ignition to the on position, count the flashes from the ECU light and let me know what the codes are. It'll give you two numbers for each code, with a pause between them, ie: Flash... Flash... Flash........................... Flash That would be code 31 See what pops up mate it may well have something to do with your start up James
