Not sure if you are referring to the problem mentioned in another thread where if you turn on signal light and turn, you will have the click click sound. But if you turn without switching on the signal light, then no click sound. When I told TCM during last servicing, they said it is normal. The technician even showed me three other latio (who are also there for servicing) and their clicking sound was much louder than mine (touch wood). So I cannot complain liao as mine is not loud.
This noise should nnot happen if the steering is normal leh!
This sound from the text above in blue is normal, if there is no sound, you signal will not auto off.
