2014 onward diff oil change?

[Nickyt]

Hi I have been looking around for the recommended intervals to change the differential fluid on the 2.2 dtec 2014 car. 
My car has only done 55k now and struggling to find any info on it?

You should replace it before it starts to knock when turning in on a tight turn (such as pulling onto a driveway or threepoint turn)
The oil can be purchased from eBay   https://www.ebay.co.uk/itm/GENUINE-HONDA-CRV-DPS-FLUID-DIFF-OIL-1-LITRE/392495346713?epid=1415923714&hash=item5b628bb419:g:t-sAAOSwSONcM4GV
