i have got the same model and i am sending mine to change the OCV tomorrow at platinum lifestyle in bagan.

it was leaking last time i checked but changing the o-ring only will not help. a known issue, according to suzuki service center. so i having the whole pump changed.
and also check for sort of steering rack sound, which i suspect is not. i had the brake pins changed recently.

slowly repairing all the things i need to repair for the car.
next should be the compressor because the air cond sucks especially in the afternoon and hot day.

try platinum lifestyle service center in bagan?
