With COVID lockdown in Sydney , I havent been able drive much .. today I took the car out and as I was accelerating from the lights at no more than 50% throttle, I heard a faint rattle /knocking noise at very regular interval about 2-3 per second until I eased off the throttle.

has anyone had similar? Any suggestions where to look? Petrol tank is half full (always use 98ron), and bought maybe 7 weeks ago at most, maybe it’s gone bad already?

We've had the same problem for quite some time now. Light pinging then massive amounts of black smoke. We got to a Subaru specialist but not Subaru and I've ofetn wondered if there was an updated tune. We only run 98 and have even tried keeping the tank above half just incase it was a surge problem.
