I’m having the same codes: 2B0D and 27BA has anyone found the fix?

2B0D - Idle Actuator Monitoring Bank 1

27BA - Fuel System Lambda / Charge Plausibility Bank 1
I am in the same boat:
27BA
2B0D
2B57

New TAs
Replaced ICV
Checked for any leaks
New Front O2 sensors

I cannot wait to get rid of this car. :)
Guys , I removed my stock Plenum and sealed the plenum tube with RTV as there was a whistle sound did some liqui moly injector cleaning , took a car for a ride and car went to limpmode and engine light, did a scan and got this :

DTC:

002BOD. Digital Motor Electronics (DME),

monitoring (bank 1)


Any ideas it could be a fault throttle actuators

Vacuum control pressure sensor or possibly - but less likely - a throttle actuator(s). Read the links below.
