As some of you know I've had vsc/trc and vsc/off lights on for over a month now after I plugged in an obd2 reader in. I've given up looking for solutions so I'm now in a Toyota garage getting it sorted . They are saying it could be the yaw sensor(£440) that's at fault,mainly because its trying to calibrate to AHC settings where there is OME suspension! Has anyone had any experience of this? Seems a bit o.t.t to me considering it drives fine and the steering is straight as an arrow!
