  1. Hi all, 2007 tdci, one morning engine malfunction and immobiliser active appear on cluster, car won't start or even crank, elm cable won't connect to diagnostics, snap on code reader will read certain modules but not engine ECU, recovered to autoelectrians, his dealer level equipment will also not communicate with engine ECU, ECU taken out and sent away for testing, report that firmware was corrupt and would communicate with diagnostics on bench test. ECU put back in car at auto electricians, still won't communicate with diagnostics equipment, still won't turn over, still got immobiliser active message on dash, all wiring has been tested by autoelectrian and confirmed ok seems strange ECU behaves on bench test but not once back in car, any ideas or suggestions .......ford have quoted £1600+vat for new engine ECU but auto electrician isn't convinced this will solve the issue ......
