I was toddling along in slow moving traffic, applying the breaks to slow down. Then a clunking sound, similar to the sound of hitting a pot hole, occurs. Immediately, the serv and ESP light comes on. Well the triangle one with the swerving car on it?! The main answers I can find relate to the abs rings which would be an easy fix. But I figured the abs would have came on? What are your guys suggestion? Are the abs rings universal? Recently had the drive shaft changed on the drivers side but the sound came from the passenger side, so thinking of nabbing that off to test it?
