I've recently got myself a 2016 Audi A3 Sportsback. 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 and 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 ideas how serious this is?
Thanks
