Ok, so we have:
P2562: Variable geometry turbocharger: Position incorrect in relation to the requirement (Not enough turbocharging).
Activation Reason: Positive discrepancy above 40% detected for 6 seconds between the position reference point and the measured position of the variable geometry of the turbocharger.
Conditions for Activation: Engine Running
Conditions for Disappearance of fault: Driving for 5 minutes when the engine is hot.
Downgrade Mode Present When this fault is active, the EGR functionality is deactivated and the Engine Management Light is lit.
Symptoms:Noise, Smoke from the exhaust, Lack of power or Loss of braking.
Suspect Areas:
- Turbocharger (Variable geometry open)
- Turbocharger solenoid valve
- Electrical harness
- Position indicator of the turbocharger
- Vacuum circuit
P1497: Variable geometry turbocharger: Position incorrect in relation to the requirement (Not enough turbocharging) (APV).
Activation Reason: Positive discrepancy above 30% detected for 6 seconds between the position reference point and the measured position of the variable geometry of the turbocharger.
Conditions for Activation: Engine has been running for at least 6s
Conditions for Disappearance of fault: Driving for 5 minutes when the engine is hot.
Symptoms: Noise, Smoke from the exhaust, Lack of power, Loss of braking
Suspect Areas:
- Turbocharger
- Turbocharger solenoid valve
- Position indicator of the turbocharger
- Vacuum circuit
- Electrical harnesses
U1F00: The BSI has not detected the occurrence of a fault sent by the ECU that recorded the fault code
B162C: Fault: accessories positive relay control and status not coherent: Relay commanded but inactive.
Cause: The control of the accessory positive relay is active even though the output of the accessory positive relay is inactive;
Relay commanded, accessory positive supply inactive (Voltage less than 5,6 V);
Fault confirmation time: 1 s
Suspect: This can affect supply of electrical components, suspect:
Fuses, Connectors, Built-in systems interface, Supplies protection and management unit.
B1818: There are a few of these, they normally have an other 2 characters after this code to distinguish, but generally relate to the oil measurement display error.
I have to ask - have you changed anything in the BSI using Diagbox? Any parameters for the Head Unit, displays etc? These last sorts of electrical issues (the last 3 codes) can be symptomatic of a mis-configuration in the BSI, so thought I'd ask....
