Remove your VIN number from there, not a good idea to post it in a public forum!

Thanks, point well made, done. Somebody has gotta really want my broken Bella to come all the way to the south of france for her ;-)

I'm sure the "20 01 03" date shows that the ECU was updated in 2003, don't know if that is the latest though.
