Guys

1. I think I kena the dreaded IAFM failure. Is zordaq the way to go? I think there’s one here in Shah Alam.

2. My boot light only turn on when halfway open/close boot. Then when fully open boot it turn off again. Any idea where to check?

Might want to find in scrapyard for a small fee. Or if you know those shop that do grill, they can make one for you.
1. What Zordaq JB did to my IAFM was put something to strengthen the channel changing rod. According to their mechanic if the rod already gone case then nothing they can do. But one thing I'm sure is they way they fix it will retain the short channel long channel function of IAFM. Some shop method is making it stuck to one of the channel so no more rattling. Recently Zordaq also advocate to replace the IAFM unit to that of Iriz, so no more variable channel hence no problem. You do that by sacrificing low rpm torque thus worse FC. Yet according to them the difference is negligible.

Worst come worst, OEM IAFM is not expensive now. Can check price on Shopee/Lazada.

2. High chance is the wire from boot lock to your boot cabin bulb broke after open-close for quite some times. Can do accessories shop to check and they can fix it for you for a small fee.

Coolant reservoir hose?

But if it's a low pressure hose, any aftermarket silicone hose should do the job just fine.
