volvo 850 awd lpt 20v combi reports?

hey people I recently bought a 850 awd blue 97 180 000 km for 300 euro. want to listen to me, what experiences you have with 850 awd. mine has zero rust except rear flap. however, the cardan shaft has horrible play. then still as small as brake slurry and antr.well.manschatten. convinced me the interior equipment. leather and wood steering wheel are noble. moreover if it has sailed or cold it is not right. so if the lpt should come he has something like setters. what could that be? end cable/distributor? because then it needs full juice? besides motor control lamp lights up. salesman says it’s not bad at 850/v70 general error. tester shows any error air mass sensor or any sensor. if you know of such a mistake please tell and experience! thank you!
