every now and then when i'm driving my VSA symbol along with the exclamation mark comes on randomly...tonight i noticed when i brake moderatly hard my e-brake sign comes along...after a second or two it goes away and the VSA symbol along with the exclamation mark comes on again...can anyone care to chime in on what the possibly diagnosis might be? i have a MY07 along with 34k miles, lowered on koni/espelir (almost stiffest setting)
