2017 BMW X1 Gearbox/DriveTrain fault *NO Drive, NO Reverse, NO Neutral Stuck in Park

HI, I seem to have a odd one here... this doesn't seem to be the very common spring locator fault as i have very different symptoms

its a November 2017 model Xdrive X1 20d M Sport Auto just less than 27,000 Miles

Car starts, but Cannot engage any gear forward or reverse or even Neutral, the Gear lever will just go straight back into Park after a second or 2 and will not try to move!

Gearbox Code - GA8G45AW

fault codes Via Autel Diag...

420097 Permanent Solenoid Valve SC4: Shut as Defective

4200C1 Permanent solenoid Valve SC4: faulty Closed or oil pressure switch for SC4: faulty off...

when cleared.. after start up go to select a gear.. pops up drivetrain fault and these codes reappear!

gearbox fluid is all new and levels checked and correctly Done via Diag Tool

under live data with Snap On Diag Tool...
when selecting Drive.. it briefly saying its going into reverse...
when selecting reverse... briefly saying its going into 3rd gear

OBD Fault codes are Permanently Stored and Cannot be cleared...
P0736 Reverse incorrect ratio
P2809 pressure Control Solenoid G Stuck On
P2743 Transmission fluid temperature sensor B circuit high

We sourced and Brand NEW Valve Body unit for the gearbox as thinking that was the Failure (The solenoid faults) Replaced, carried out the Necessary Adaptions..
Exactly the Same faults

not under warranty im afraid

Thankyou in advance for any help

Regards Matt
