55 Plate Zafira 1600 petrol - warning light - freman

The above vehicle belonging to my daughter in law was serviced by a local garage in February & for the last few a warning light showig a spanner has appeared on the dashboard.

The garage has cleared it several times, but it re-appears after a short time.

Apparently the vehicle drives well & the oil,water& brake fluid levels are O.K.

Any ideas anybody please
