Backround,
2010 bmw 335i n54 e92
Fbo 5.5ic
Mhd 2+
New bosh plugs, delphi coils,
Hks bov
have had misfires in the past, i had over boost 19.5 so i changed boost solenoid and vanos, reset all adaptations at the same time, now experiencing under boost at 16.5 target 18 nocodes for underboost. After adaptation reset bov has a reduced noise only making decent noise at high rpm. Car run ok but boost lag is very noticeable.

Current codes
At cold start 2A7A- camshaft position sensor,exhaust cold start, followed by 3100 boost deactivation, once car is turned on off two times boost is returned.
Since this issue started something near my downpipes is rattling during warmup
misfire 4 (eventually multiple random-misfire or in pairs 4&6 mfirr or 1&4, or 2&4)
If i drive on for some time i get 2a87 exhaust vanos mechanism, they are brand new, i tried swapping.
I am doing valvecover as a small leak was identified, plugs and coil refresher as well.

Any one have similar issues? Do i need to clean the vanos component tucked on the other side of the wire attached to the actual vanos? After adaptations the reduced bov is concerning me, is it normal to have a reduced bov after adaptations reset?

If you need some vanos solenoids. I have a used set that I pulled from a wrecked 335i. Let me know, and we can work something out for cheap.
