Hi can anyone help me with this engine management fault my car is a 2006 2.2 Diesel the report was done by the RAC and if anyone has had this issue what does it mean how a rough cost to get repaired if possible the engine management light comes on and off and when on doesn’t affect the drive 

 

 

 

 

System Type: ENGINE
Name: EOBD
DTC: P1384, , Manufacturer controlled DTC
DC: P2004,Intake manifold air control actuator , bank 1 - actuator stuck open
Intake manifold air control solenoid, bank 1 - solenoid stuck open
DTC: P000C,Intake camshaft position A , bank 2 - slow response
DC: P0008,Engine position system , bank 1 - engine performance

 

I would say that a carbon clean from a company like TerraClean would sort these issues.
Sounds like carbon build up in the intake side of the engine
