At SC now doing my 1k service @1100km. Changing the engine oil, 3.6L of 0W-20 for RM 145. Hopefully they manage to fix my rattling noises as well.

2nd review after 1100km and some highway driving

Wind noise - none till about 130km/h and it gets progressively louder as the speed climb.

Road noise - quite apparent especially on the rougher surface. No improvement from the FC (or maybe a downgrade?)

Engine/cvt noise - the CVT noise is more muted than before and I could barely hear the engine/CVT noise even at 160km/h @ 4k rpm. Tire noise a plenty that drowns everything

LKAS - works wonderfully. Doesn't bounce around, stay in the lane nicely (abit slightly to the left of the line, so if there's a car on the left, I'll have to pull the steering a little to the right). Day/night no issues detecting the lines and no issues navigating the bends at NSE. It's a nice touch when you hit your signal, and the LKAS deactivate then auto re-activate when your signal is off. 

ACC - it's bad. there's a point it braked hard at high speed because it detected a car on the other lane. Acceleration and deceleration is not linear and multiple sudden brake incidents. Such a shame when LKAS works so well but ACC is bad resulting not much point in using LKAS.

Overall fuel consumption - 13km/l (about 700km town and 400km highway drive). Best was 17.8km/l when I was cruising between 110-140km/h.

Long time ago when faced rattling, Global Amity Bangi resolved my case. Other SC kinda as u, wrote solve via etc2

I am a very DIY person,
