This has had a few issues previously, but not all. So a newer one was developed & installed from a particular VIN onwards, therefore not all vehicles require the replacement to be done.
If you have not had the Q093 carried out, I recommend doing it sooner rather than later. It does fix a few quirks that makes ownership a lot more pleasurable (not that its that hard).
