S80 v8 electrical issues
I have just purchased an s80 v8. It has a few miles on the clock and some minor issues which are easy to resolve. However it has started to throw up a message of immobiliser fault on occasions at which point it will not start. I have scanned it and it comes up with multiple communication errors for the ecm. I have checked the ecm and there is no water damage or or obvious issues. I have a launch code reader but no volvo specific stuff. Can anyone suggest what I should be checking for. Are there known faults to check first. Car is a 2007 s80 v8. I can diagnose things myself but just need some help to start as I have never dealt with volvos previously. Thanks Mike

Key issues
My launch code reader communicates with all of the modules and I can see it throws up multiple errors for abs srs and immobiliser communication issues. These will reset if you keep clearing them. I have observed recently that it does not always see the key as mine is keyless. If I insert it in the slot this sometimes works. Other times I just lock and unlock it and that's enough. There is no one way that seems to work every time
I have looked at the kvm module and it has 2 keys registered and sees my key in the vehicle. There is a reading which says something like key detected but not authorised. I am now fairly sure that it is an issue with the key and whether the kvm module sees it. I am waiting for a local locksmith to get back to me to see if he can help read the key and module or possibly make another key. I will report back once I spoken to them. Incidentally my friend has had similar issues with his jag xf so it makes me wonder if it is something to do with the ford architecture.
