Volvo XC70 built in 2003, issues do not stop

hi,bin new here. have used us 15 months ago a Volvo XC70 (built in 2003) at the dealer,and gave our most beautiful V70 in payment.Tja,probably the worst mistake.I don’t know.First a front spring had broken,then Xenon lamp broken,motor suspension torn,then alternator,back flap no longer went by itself high-new dampers,charge air cooler defective and different hoses replace. TODAY I want to go,ad “NO ÖLDRUCK,BITTE MOTOR Turn it off again, battery jammed off, hm, didn’t go first, then turn it on again, now it went again.Did anyone ever have this problem? Do you have such problems with your XC70 (built in 2003)? I don’t know any more.Can’t just work for the car, it’s also for driving and not just to put it in the workshop.
