Hi i’ve got a mercedes a180 2017 my cars just been in for recall today for drivers side airbag. so i’ve gotten into my car and an engine managment light is on! AND the airbag light is also still on so they didn’t even do the job which was meant to be done! The man at mercedes said i’ll have to pay to get the engine light off even though it’s only came on when it’s gone into their care. I’ve had the car for about 4 months and no engine lights have ever been on. Also loads of marks into the interior of my car. What can i do as i clearly shouldn’t have to pay for this when it’s come on after coming from a recall! Thanks
