No, not yet.
I have sent the car to Nissan Service Centre 4 times..
1) First, on 23 Dec 2016 - they asked me to come back if problem persists (where I had very serious cough for 2 months until after Chinese New Year)
2) Then on 9 Feb 2017 - no air-cond technician available on that day
3) Then on 11 Feb 2017 - all full booked, they scheduled my appointment to 16 Feb 2017
4) Then on 16 Feb 2017 - again they re-scheduled my appointment to the following week (because they have only one air-cond technician at the centre)
So, untill now, I am still waiting for my appoitment next week.. which they also told me I have to leave my car over-night, and, as a matter of fact, they told me they have not seen & have not encountered this kind of air-cond (white film) problem before..

To ascertain the risk of those white films (allegedly Aluminium Oxide),
1) I have sent an official "customer care request" to Nissan Malaysia Website on 8 Feb 2017 (http://www.nissan.com.my/?gclid=CjwKEAiA8JbEBRCz2szzhqrx7H8SJAC6FjXXTLibLTBeSvFFdDozvPdzKUEwzQR8xoMH3zHMkaaLiBoC26fw_wcB#) - But until today, No Reply.
2) I also sent a "technical assistance request" to Nissan Motor Corporation Japan on 10 Feb 2017 - But also, until today, No Reply.
