Started up next morning and went to drive it and had no power.
Symptoms- Long throttle travel. Very slow to increase rpm and road speed till the rpm reaches about 2000 and then picks up rapidly but throttle still not really responsive.
Nanocom has a message
Exhaust Gas Recirculation B code P045C control circuit low
(pending)
general failure information
Have searched posts and there is on with similar symptoms and it was suggested that it will need EGR replacement.
If so does anyone have any idea which one could be at fault
Any help pls.

This is from the Workshop manual but are not quite the same codes.
P0405-21 Exhaust Gas Recirculation
Sensor A Circuit Low - signal
amplitude < minimum
Right-hand Exhaust Gas
Recirculation (EGR) sensor
circuit low - signal
amplitude less than
minimum
EGR valve position sensor
circuit short circuit to
ground
EGR valve position sensor
fault
Check the right-hand Exhaust Gas Recirculation
(EGR) sensor and circuits. Refer to the
electrical circuit diagrams. Using a data logger
function, check the EGR valve angle. With the
ignition on, engine off, command the valve
actuator to 0% pulse width modulated (PWM),
and then to 100% pulse width modulated
(PWM) and recheck the EGR valve angle. The
value should range from 0 - 20% to 80 - 95%.
If this is not the case, install a new sensor.
Clear the DTCs and test for normal operation
P0406-22 Exhaust Gas Recirculation
Sensor A Circuit High - signal
amplitude > maximum
Right-hand Exhaust Gas
Recirculation (EGR) sensor
circuit high - signal
amplitude greater than
maximum
EGR valve position sensor
circuit short circuit to power
EGR valve position sensor
fault
Check the right-hand Exhaust Gas Recirculation
(EGR) sensor and circuits. Refer to the
electrical circuit diagrams. Using a data logger
function, check the EGR valve angle. With the
ignition on, engine off, command the valve
actuator to 0% pulse width modulated (PWM),

P0407-21 Exhaust Gas Recirculation
Sensor B Circuit Low - signal
amplitude < minimum
Right-hand Exhaust Gas
Recirculation (EGR) throttle
position sensor circuit low -
signal amplitude less than
minimum
EGR throttle position
sensor circuit short circuit
to ground
Check the EGR throttle position sensor and
circuits. Refer to the electrical circuit diagrams.
If no fault is found in the circuits, install a new
EGR valve. Clear the DTCs and test for normal
operation

) didn't need anything done, but later ones you do need to have something done to ECU. Either a BAS tune (if they support your year of D3) - which can then be loaded with a GAP tool. Or, as has been previously mentioned getting a tune done.
