Have had my SE LR just over 6 months and been using ACC/traffic jam assist throughout that time with no issues. Over the last few weeks it has developed a scraping noise when the car is braking with either activated. Only seems to happen the first or second time the car brakes and then is fine. If I use normal braking I can't replicate it so don't think it's an issue there but not sure what else it could be. Anyone else had a similar issue or have any ideas what may be causing it? Have started cancelling ACC when approaching traffic to avoid it happening and will bring it up when the car is due it's first service in a couple of months. Thanks
