hi there, i have exactly the same problem. would love to know if you get anywhere. i had the injectors recoded this evening and it made no difference. similar to you the light is flashing, you can clear it and the light is still flashing before you even start it. so cant be an injector fault. my mate is a specialist in injectors and said they are very simple only thing that goes wrong is the valve in them. which wouldnt give it an fault code when not running. im thinking ecu but would love to be sure. if i have any luck ill let you know.
