This morning I engaged the services of a firm called UK Diagnostics based in Ilford, Essex, in my efforts to avoid the perils of Mr T and finally discover the mystery of what was going on with my VSC-TRAC/VSC On warning lights. What they came up with was this:" C1336/ Zero point calibration of deceleration sensor, undone". They said this could have something to do with my recent upgrade from 16-18" alloys. They ran a full diagnostics and everything else was coming up fine, apart from this C1336 code. Does anyone have any idea of how I should now proceed, as these damn warning lights are still on and driving me to distraction?
