Signum ECU Wiring/Pinouts

[kildrum]

I am looking to trace a suspect wiring loom fault on my 2004 CDTI Signum 150. I have read about many similiar faults on this forum about this exact year and model having this generic fault, which usually has turned out to be a dodgy connection/broken wire feeding the power to the ECU unit. I brought the car to my local Vauxhall dealership to have it put on the computer, but it turned out to be a waste of time as the diagnostics equipment couldnt communicate with my ECU. The technician advised me that it looks very probable to be a broken loom wire. All help and suggestions would be greatly appreciated. Thanks in advance.

Hi there, Thanks a million for your assistance. i am really at the end of my tether with this car. Its a 2004 1.9 CDTI 150 Diesel Signum and the ECU unit is behind the drivers side front bumper. By removing the front d/s wheel arch liner gives you full access to the unit. Its a Bosch LM 0281 011 449 and 55 189 630 model numbers on it?
Fingers crossed
