My whistling S9 AutoSet has a country code of 23 which I understand represents Singapore.
What other county codes are there, are S9s made in all of these and have S9s made in these countries too been afflicted with the whistle-on-exhale problem?

So my current S9 is from Singapore and was made sometime in 2013 (serial number starts with 2313xxxxxxx) and has SW SX474-0907, BID SX525-0300, VID 1, RID 100 and HID SX496-0212, Ref 36005A, Lot 505537 and serial number 231311xxxxx, obtained August 2013, FWIW.
Does anyone with an S9 made in Sydney, Australia (serial number starts with 22xxxxxxxxx) have the whistle-on-exhale problem?

Has this issue disappeared? My machine is still whistling.
I had been waiting for an explanation from my supplier but never got one. Instead my machine is finally being replaced under warranty but can I expect to get a new one that will it likely be free of the problem?
What are the manufacture dates and s/w, firmware versions that people are seeing now?
Is there anything else that you can think of that has changed in the past year about these S9s, anything that I possibly need to watch out for in terms of getting a replacement?
Now I see that there is the new so-called "S10" available. I guess I'll have to see if I am offered that instead, unlikely for a warranty replacement. I wonder if the S10 also (sometimes) suffers from the whistling on exhale noise?
I have had mine since 20 Sept 2014 and my machine's serial number:
- The first 4 numbers of my machine ... 2314
- The first two numbers: 23 denote made in Singapore (22=Australia)
- The next two numbers ... year of manufacture: 14 ... 2014
So my ResMed was made Singapore in 2014. So far, it is very quiet and has no whistle; I have been using it nightly since I got it on 20 Sept. The APAP has 348 hours use on it.
So far so good.

Better living through CPAP/APAP machines!
That is promising news. Not all older machines were affected either but it's good to hear that there are 2014 machines without the problem. Thanks.
