Will do what am I looking for live data wise?

Car has ran fine for two days the. This evening from cold went for a drive - perfect. Parked for 30mins got back in flashing eml stalled and running like a pig (no where near as bad as before with maf off mind) I just pulled out of the drive out my foot down and she was perfect again, lights all off. Stopped for fuel started again fine when I got home plugged the reader in and there were no faults wtf!!!

Good news - smoke test came back showing the bung had been left off the pcv! Guessing that could cause some issues! Is there more than one place the bing could go though as I watched the guy put it on unless he didn’t push hard enough - wondered if he could put in wrong place? Also nozzle for c8 gas was loose so will cover in gasket seal and tighten her up.

Now that’s sorted (hopefully)

Here she is idling - does this just sound like the standard vanos rattle to you firstly? Secondly in the background there is another noise no idea the source of it but it sounds like a resonating? Any thoughts? Cheers all
