I own a 2005 xc90 T6 I have the message pop up Power system service Urgent wth the Red Triangle and red battery icon lit up. Car has a New alternator and New battery. The Alternator is putting out 13.8 amps. I have no issues with the vehicle other then the message and the lights on. Car charges and runs fine. I have been keeping sn eye on it for a couple weeks, are there any other possible answers for me other than replacing the central electronic module?
