Blue sky brain storming ....back set is 18 mm taller than front, shouldn't make a diff unless maybe the ESP does a compare on speed from front to rear(?).
The rear speed sensor reads off the wheel bearing outer race, if the bearing was not quite ready to fail, but close, that MIGHT be causing the glitch. Or a bad wheel sensor. A STAR diagnosis would pinpoint the specific wheel sensor if that were the case.
Might be time for a Stealership trip, or some of the really smart folks here may chime in.
