My Dynamic Stability Control sensors on the Brake Master Cylinder failed giving me a Dash Warning Message.  The sensors were replaced and the Warning Message disappeared but left a blinking Warning Light.  To cancel the Warning Light the DSC System requires synchronisation by Dealer tech & software.  The Dealers I have contacted no longer have the software required and I am stuck with the Warning Light issue with an MOT approaching!  Anybody had this problem which seems to be a tech threat to emerging classics.  Thanks.
