Hiya everyone new to the fourm I have a 2009 v50 2.0d won't start after flat battery comes up with imobaliser fault try again have run a diagnostic and comes up with codes ecm c326 communication control module faulty signal ecm0625 genarator signal to low can any one help been ready up all day but can't seem to get a definitive answer

You will have to get it towed to a volvo dealer who will have to reload the Engine Control unit with the original software . This is an odd engine which can loose part of it's memory if the battery has been flat for a couple of days or more .

.... Clan gives you a definitive answer in under an hour and a half. OUTSTANDING.

Than you clan for your help that's what I was beginning to think seen lots of your posts before keep up the good work
