I searched for a similar topic, but could not find anything similar.
My S90D is a couple of weeks old now. I love everything about the car, but one thing nags me: when on AP, in stop and go traffic, the brakes engage - in a pretty abrupt way and quite late IMO - but what bothers me the most is a relatively loud 'thump' when the brakes engage. It sounds like a mechanical something (pump?) engaging (which would make some sense I guess), but it could also sound like a loose something (caliper holder?) in the braking mechanism.
Now, the same *does not* happen when pressing the brake pedal, regardless of how hard of a stop. The sounds comes from the left/front (driver's) side. It also seems to be louder if there was an acceleration shortly after followed by a brake (to zero or close to 0mph).
Anyone noticed anything similar to this? Not sure if I should be worried or just get used to it...
