Hello atalante83
Sorry to hear your engine light is staying on. How is the engine running? Mine seems to be running as normal. I had a large amount of oil from the air filter at the time the light came on.
My light is still on, waiting to hear from Morgan this week.
If you click on the link posted by Red Three above it will take you to a TM thread on the subject and where to find the USB diagnostic plug.
