I have been trying to chase down an injector fault for a few months now and I'm completely out of ideas.

Last vagcom scan shows

18072 - Control Circuit for PD Injectors
P1664 - 000 - Electrical Malfunction - Intermittent - MIL ON
Freeze Frame:
RPM: 2163 /min
Torque: 216.0 Nm
Speed: 49.0 km/h
Load: 72.9 %
Voltage: 14.06 V
Bin. Bits: 00101100
Temperature: 79.2°C
Bin. Bits: 01010000

So far I have replaced the injector harness inside the head. Removed the entire wire loom back to the ecu and patched a few wires that had rubbed through their insulation, and replaced a leaking tandem pump.

Lift pump can be heard moving fuel when key is turned on

Any help would be very much appreciated
