I hear you... its a puzzler and a conundrum that must drive you crazy... recently did a full suspension upgrade, bilsteins, springs mounts and the lot. Drive a few hundred miles, yellow DSC and brake light. Alignment done, speed sensors checked, wheels balanced - rubber all new, codes interrogated etc etc - steering wheel alignment components tested - all AOK. So I have to live with it. vehicle runs like a champ and handles like a fighter! Drives me nuts as there has to be a reason and one day I will get to the bottom of it... but its a daily driver. oh I have been doing that spin wheel left right and center slow thing start of each drive day... what good it really does is only measured in the time between failure events - when the dreaded DSC beep and then brake fault appears and the cycle is repeated.
