Renault Trafic Airbag and SERV warning light

Hi. I have just picked up my 07 DCI 115 renault trafic after having 4 fuel injectors replaced. After driving away from the garage I noticed that the SERV light was lit and the airbag warning light. These were not lit prior to the vehicle going in for the work. Is there something that I may be able to check and fix or would it be best to return to the garage where the work was done.



Many thanks



Andy
