I have working quite hard to care for and maintain my '04 XC90 T6, but there always seem to be some little annoyance that is just flat out irritating. My latest is the "message center" that gives me warnings that I'm not even sure are legit. First, it was after I made a u-turn during a rainstorm and I got 2 messages that said something to the effect of "Anti-Skid Service Urgent" and "Brake Assist Urgent" this also included the ABS light coming on. Shortly afterward, those messages and the light disappeared. Now the other day, I get a message saying "SRS-Airbag Service Urgent" but the airbag light comes on with the ignition and immediately goes off. This message has so far not gone away. I'm not quite sure what is causing the "ghosts in the machine", but it's getting quite annoying. I would take it to my local Volvo dealer, but I really can't afford it right now just to reset it, if that is in fact the issue, or tell me it is something worse. Like I said, I don't even know if these messages are accurate or not. Any thoughts about what I do here? I know that according to the CarFax, there has been some modules replaced over the years, and know water damage. I just want to find out if this is something serious or just me chasing a ghost.
