Hello and I hope someone can help me. I have a 2006 c3 1.6 hdi, Tuesday I drove home 50 miles from work with no problems, half hour later got in the car and it wouldn't turn over. Had all my ignition but nothing when turning the key. The AA can out and diagnosed a dead battery.
So today I fit a new battery and the same thing, have dash lights but no cranking, car keeps going into 'economy mode ' after a few mins as well. I have noticed that with the ignition on I can't hear the fuel pump..
Any ideas gratefully received
Cheers
Tim

Hi treehack,

If the engine won't turn over and the battery is ok, suspect the starter motor/solenoid unit.

It did cross my mind but the absence of the fuel pump whirring is leading me to think its immobilise/ecu related

The immobiliser just stops the engine firing (by stopping fuel through the injectors), engine still turns over.
