I've replaced an ECU on a 2001 (51 plate) Astravan 1.7dti Sportiv.. The engine runs perfectly but the MIL light (car with a spanner) is on all the time and the error codes will not clear:
P0480 Fan Relay 1 Signal Low / Open
P0481 Fan Relay 2 Signal Low / Open
P0381 Glow Time Telltale Circuit Voltage Low
The replacement ecu was from a 2001 Yreg 1,7dti Envoy which is a slightly lower spec.
I believe the first two errors are because the new ECU does not have A/C enabled (I've checked this with Tech2) and when I can get TIS approval I will enable it... But the last error is basically saying the Glow plug light doesnt work.. Now I've never seen the glowplug light come on before so could it be possible that the 51 plate doesnt have the bulb and the Y reg does? seems a bit strange.. Or could it be coincidence that the bulb has gone at the same time as replacing the ECU?
Thanks in advance for any help
