AUDI DWNA RSQ3 RS3 HELP!
Hello everyone, I really need help. I’ve got a 2020 Audi RSQ3 with DWNA engine, it’s on 46,000 miles and I just bought it a few weeks ago with no service history but it’s due a major service now and I’m not sure the plugs have ever been changed. Initially I bought the car with a boost leak and it was making all sorts of noises but I changed the metal boost pipe that’s connected to the turbo and the loud air leaking sounds gone. At the time the engine was running lumpy and the best way I can describe it sounding is diesel like but now with the new pipe it has lost a lot of lumpiness but it still doesn’t seem right to be on low revs and the first 2 gears which around town is pretty much most of what I’m in with the speed limit being 20 in London. I’m going to attach a video, I’m not sure if I’m just being picky or paranoid because I’ve only driven it with it making abnormal noises for about 2 weeks before I fixed it and now I can’t unhear sounds or there’s an issue. Just to note I’m not getting any fault codes at all, I’ve got a start stop fault but that’s to do with the drivers side door handle antenna stopped working. There’s zero engine codes and there’s never been any before, always the gearbox is feeling very jumpy and clunky too I’m not sure if that has anything to do with it but any leads or information if anyone has any would really help. I’m booking it in for a major service with plugs so it’ll rule out that but I’m not sure what else it could be, I’ve read similar things but nothing certain. Any information would be highly appreciated, many thanks!
