Problem Description

Dear sir, 

my Q7 had a flat battery I jump start it & went to Audi Centre they fixed it by saying that battery terminal was loose & also I ask them to change AC air filter.after work they took Q7 for test drive & took a while & when they came bk & handover my car it has a engine check light ON & when I ask them they said ok we check & now it’s been 2wks they can not fix the light even when they hand over me car it has a slipping transmission too which was surprising for me.
