Hi, through a momentary lapse of concentration i have managed to graze my rear alloy against a jaggedy curb, probably no more than 5mph, I wouldn't be too traumatized as they needed a refurb anyway, i'm more concerned the ESP light came on 20 miles after and stayed on for the rest of the journey, it went off and stayed off on restart, but has come back for short times over the last coupe of weeks. I presume i have disturbed the tracking rather than a sensor fault. Any advice or experience of the same? checked for fault codes and none logged.
