GOLF 2010 1.6 TDI P0203 Help

evening, any help would be appreciated,

I have a Golf 2010 1.6 TDI, engine light came on fault codes as follows

  IDE03896-ENG102925   Injection valve 4: voltage-V_INJ_MAIN[3] 142.95 V

i thought i had a prob with injector 2 because that is the only injector with 0 volts, but what i dont understand is why i am not getting any movement on injection amount deviation across all 4 cylinders

any help would be much appreciated also very new to using VCDS

thanks

Imran: I'm sure that your decision to post-up a partial copy of an auto-scan report for the car has been prompted by the desire to focus reader's attention on the problem - but the missing bits from the auto-scan provide a valuable context for diagnostic analysis.

So- to enable us to fully consider the data-rich environment for the DTCs in your post - please provide a complete (meaning UNEDITED) copy of an auto-scan for the car.

Deviations probably won't change while there's a known fault with the injectors.

I'm not sure what to make of the discrepancy between the fault code for Cylinder 3 vs the lack of voltage for #2. Possible ECU software bug? It wouldn't be the first time something like that happened.

Theoretically may be short circuit between wires to cyl2 and cyl3 injectors. Or internal short in ECU.
