Car Jerking (misfiring) in all gears Galaxy 2.0 TDCI

[Markgul]

Hello,

My Ford Galaxy 2.0 tdci 2007 has started to misfire when driving. The car jerks when driving as I put my foot down on the accelerater. Since having this issue I have done 2 trips each 250 miles. The car picks up speed fine. I have taken it to 100mph and no issues apart from jerking everytime I press on the gas pedal. This happens in all gears. The error codes from forscan are:

 P1335 - EGR Position Sensor Minimum Stop Performance

Additional Fault Symptom:
 - Circuit Voltage Out Of Range

And
===ABS DTC B1B69:16-08===
Code: B1B69 - 12 Volt Supply Circuit

Additional Fault Symptom:
 - Circuit Voltage Below Threshold

Status: 
 - Previously Set DTC - Not Present at Time of Request
 - Malfunction Indicator Lamp is Off for this DTC

Module: Anti-Lock Brake / Traction Control Module

===END ABS DTC B1B69:16-08===

Any help much appreciated.

Thanks
Mark
