Hi all, New to forum having got second hand 2018 S3 saloon this year and lets say things aren't going to smoothly. Just wanted to see if anyone is having/had the same issues I'm having. Start/Stop works majority of the time but has the tendency to completely cut the car out, which is fun if I don't notice the tacho go to off opposed to ready and try to set off. Got a ghost immobiliser to so can take a while to re-start which feels like a 3 years at a set of green traffic lights. The start/stop is very abrupt at times when it is working and jolts the cars when coming to a stop too. On a cold start seems or be a gravely rustle noise from the gearbox especially if I engage neutral which disappears when it's warm. Should mention its a S-Tronic gearbox too. High frequency metallic rattle when on full boost from time to time but again not always. Cruise control cutting out when hitting bumps, and I mean not big bumps just the usual small pothole/sunken tracking in the road. Have got it booked in with Audi end of December, the closest they had with current circumstances but would like to go with some idea's of what may be causing some of the issues or if these are things I might have to live with. Apart from that cars great haha!
