Car Jerking (misfiring) in all gears Galaxy TDCi 2.0 2007

[markgull]

Hi,

My Galaxy TDCi 2.0 2007 has occurred a fault where pressing the gas pedal makes the car very jerky and seems like it is misfiring. Since having this issue, I have covered over 500 miles on the motorway and it seems to drive fine apart from jerking every time I press on the gas. I was even able to take this to 100mph and it was fine.

I have done a scan with forscan and this points to an EGR problem, however I’m not sure this is what is causing the issue as the car seems to pickup speed fine and the only issue is jerking. I have two error codes:

===PCM DTC P1335:1C-2F===
Code: P1335 - EGR Position Sensor Minimum Stop Performance

Additional Fault Symptom:
- Circuit Voltage Out Of Range

Status:
- DTC Present at Time of Request
- Malfunction Indicator Lamp is Off for this DTC

Module: Powertrain Control Module

Diagnostic Trouble Code details

Possible causes :

An electrical fault in the EGR control circuit.

Sticking EGR Valve

Do not renew any components until all pinpoints associated with this DTC are complete.

===END PCM DTC P1335:1C-2F===

===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

Diagnostic Trouble Code details

There could be a low supply voltage and it is below the threshold level for the system to operate.

There could be a high supply voltage and it is above the threshold level for the system to operate.

There will be other DTCs set in the ABS module.

There are DTCs for other modules.

Note: This DTC may set after a 24 volt jump start.

Discharged or faulty battery.

The generator is undercharging

DO NOT replace the ABS module based on this DTC alone.

Perform these checks

Check Supply Voltage

Check the battery charging system.

Check the condition of the battery.

Check for non-standard accessories and vehicle modifications

Check the wiring and the appropriate fuse.

Check the terminals are secure and not corroded.

High resistance in wiring

Fully charge the battery then carry out the Battery Capacity Test.

Check the power and ground circuit.

Check the connector for damage or contamination.

Check for an open circuit in the wiring harness.

Check for a short circuit to the ground or battery.

Check the condition of all cables and connectors for broken cables, damaged insulation, contamination, water ingress and loose connections.

Check the condition of all cables and connectors for broken cables, damaged insulation, contamination and loose connections. Make sure there is no continuity to ground or supply.

Check the ABS module connections for damage, water ingress or corrosion . If any contamination is found, clean the connector and ABS module terminals.

Check the ABS module fuse.

Check All Other Modules On The Data Bus For Function And DTCs

There will be no CAN communication.

If the DTC is CMDTCs and historically this may be an intermittent fault, the cause of which cannot be identified at this time. The customer should return the car should the fault reoccur noting the conditions at the time of the failure like the speed and application of the brakes.

Additional Information

The ABS lamp is illuminated.

The ESP lamp is illuminated.

There will be an ESP malfunction warning displayed on the driver information text panel.

The EBD Warning Lamp is illuminated.

Any help would be much appreciated.

Many Thanks,

Thanks Matt, I've had the EGR replaced but still same issue. I'm not sure if the blanking plate will work now?
