I've recently got myself a 2016 Audi A3 Sportsback. The car feels ok apart from if I give it high revs in sports mode the glow plug warning light starts flashing. It doesn't happen in economy mode. When I pull over, turn the car off and then restart it I get a warning about the start-stop function not working. Once home and the car has been left for a while the car in fine.

Has anyone got any idea how serious this is?


Thanks
