You start the car, the lamp comes on.
Do you immediately shut the engine off and restart the car and the lamp does not come on or you drive it (lamp stays on), shut it off and restart with no lamp?

This could also indicate the throttle body is carbon fouled and won't allow the TB to close completely or stick on occasion. It is a common problem on EFI, especially with GTDI as CCV/PCV fumes are ingested into the fuel intake at this point.
It may occasionally stick and free itself thereby canceling the warning lamp. It must not be a stored code as it comes and goes. There is a lot of difference(s) between a code reader and scan tool.
Ask then to check for this and needed THROTTLE BODY SERVICE if not a DIY.
