Range rover sport l494 sdv6 no vacuum on bank 1

hey all , got a weird one here
Range rover L494 3.0 sdv ,2015, had a Map sensor code come up P006A-00 then restricted performance, not convinced its that as the live data looked ok , Cant hear any intake leaks , looked at the MAF live data Bank 1 nothing and reading zero, Bank 2 reading ok .
Cleared all the codes went for a run ,same again
Took the MAF out both air boxes and bank 2 sucking like a hooker on steroids but not a thing from Bank 1 completely dead, away to do a smoke test but surely to feck would hear that bad a leak , what am i missing on this bloody rangie

The 2nd MAF will have no reading, as the secondary turbo was not spinning. Completely normal Thumbs Up

P006A is usually a boost leak

If its not a boost leak, then better diag gear is required Thumbs Up

looks like its the turbo shut off valve , tried exercising it with the autel and it opened slightly then gave me some vacuum then sh*t itself again , looks like its seized shut, freed it up and seems to be ok now
