I have an 05 Golf with the PD 1.9 TDI. Car has been interm cutting out, with the ecu showing a fault for the injector drivers. This went on for a week or so. Looking at a schematic all the wires for the injectors go to the ecu. I tried an overlay of the common ground (since the car completely dies) and it would interm die still the same. Car now won't start at all, and I can't comm with it using VCDS. I pulled the ecu, and it looks like it's been opened previously, as all the ecu screws are painted red? The person I bought it from said he thought it was flashed by xxx-usa? I'm planning on buying a replacement ecu, and trying that next. Does anyone have any input on how to match the new ecu to the cluster? I'm assuming it has some sort of immobiliser? I am also wondering about now not being able to communicate with the potentially bad ecu. I'm more familiar with ME7, and haven't done anything, and know very little with these EDC16 ecu's. Thanks in advance.
ECU number is 038 906 016 Q
0281011812
EDC16U31

Thanks for the help, man. I assume by "open the ecu" you mean I need to bdm it?

Open the ECU. BDM read it, most likely it will still respond (eeprom, flash, mcu).
Write the data to your new ECU, you will now have a 100% clone of your old ECU, start the car.
EDC16 is easy - EDC17 is where shit hits the fan.

Thanks for the reply, both of you! I have a bench harness I use to BDM MED9's because my BDM tool won't supply 12v+. I tried using this on the new EDC16 (same looking plug) and VCDS won't connect, nor will it read via BDM. I plugged it in the car, and I could then at least comm via VCDS. Guess I need to find a spare ecu plug, or fix the BDM tool.

Thanks, k0m. I'll print out a wiring diagram tonight. |

12v/ground are the same.
ignition is pin 18 on edc16, instead of 87/92 on med9.
