2008 335i N54 ( 2ABD error )

[Pulseleo]

P.S - VERY sorry for posting on the wrong page... Please take down my post if i post it wrongly

Hi guys! Would like some help as everytime ( 8 out of 10 times ) when i turn on my car i will have an engine error code, when i scan with BimmerLink i get the code 2ABD which is Boost pressure sensor. What should i do to get it remove? as if not the car is mostly on Limp mode?

Things i did :
- Twin Turbos are all new
- Whole intake brand new ( with HKS BOVx2 )
- Turbo inlet pipe all brand new

Things i have not tried but will do
- Change/Clean TMAP sensor?
- Change Turbo Boost Solenoid Valve? ( ordered 2pc to try )

Anyone facing this issue ? Can I get some opinion from all the gurus in this forum
