Since its on latest iStep (ECU) software the knock sensors are more sensitive than say 2017 S55 Software. As long as its not knocking under 100% WOT its no biggie could be so many other reasons too like temp/gas as I've seen in my pump gas logs.
As soon as I switched to E30 OTS (E85 cleans all that garbage) haha
