I have had my R lowered onto Eibach springs and had a full 4 wheel alignment on a hunter machine, no issues with ACC.
When I had mine realigned (standard height) the guy at the garage said he needed to advise me that the sensor would need to be checked along with the lane assist camera. They didn't have the kit to do it but knew somewhere that does and they will charge around £600 to reset everything.I was only having the toe changed slightly so I told him to crack on as I'm sure that adjusting that wouldn't affect the sensors and as far as I can tell I was right. Everything will works just as it should.The receipt has written on the bottom that the ACC sensor has not been adjusted.
