Has anyone heard of this and what is it? Engine management light came on today on the motorway and a warning saying "emissions workshop" Put it on the diagnostics machine and it came up with "airflow speed compensator flap" Cleared the fault code and drove for another 6 miles and as yet it aint come back on.....does anyone know what it is? and is it an expensive fix if it comes back on?:confused:
