Volvo Repair: 2003 Volvo S60, volvo dealer, volvo s60

Question
I recently bought an 03 S60 and have encountered a few problems.  First is a message reading 'Engine System Service Required'.  Second is my alarm goes off regularly for no apparent reason, every time I return to my car there is a message 'Alarm Triggered Check Car' but only once have I received a message 'Alarm System Service Required'.  And lastly I am now having trouble with my sunroof - it periodically gets stuck open and won't close or even sound like it is trying to close, than a few days later I'll try to close and it will work.  Can ya help?  Thanks so much

Answer
Summer, 2 of the issues are related.  One is you are haveing an issue with the alarm module.  This needs to be checked out by a Volvo Dealer or shop.  Sunroof is tied into that module believe it or not.  Engine system service also means the car needs to be scanned to see whats going on.  Roger
