My car has developed an issue in last few days where it won't start every time. When it won't start the ignition lights up fine and everything is as normal but final turn of the key gives nothing but a single click.

I changed the battery after first failed start and was ok for a day or two.

When you try to start the car and it does start, it starts no issue. Then generally speaking you will park it up and the next attempt it wont start even after numerous attempts. Return to the car half hour or hour later and it will fire straight up. Tried the spare key as thought it may have been this but still no luck.

Last thing to add to this is we have had an error message on two occasions that said something along the lines of "Start prevented"

Any advice is greatly appreciated. Im thinking maybe removing CEM and sending to volvo diagnostics for refurb.
