Clutch in V70 III defective after 80,000 km

Hello guys, I recently had a passing clutch in the V70 III D5 year 07/2009. Car was driven only on long distances and gently. At my “old Sweden”, a V70II D5 it was still ok after 385,000 km. Now at the new and greatest possible protection she says goodbye with 81.000. Has only started the soot particle filter cleaning cycle to reach through, 6th gear, mountain high with 1800 rpm. Now, 2,000 km later she did it just like that. Had already noticed, since ss the pressure point comes later, but I didn’t think anything about it. According to the travel book, 40,000 km of highway are included, without a single switching process. Has anyone ever had similar experience? I read in the forum that there was an XC60 with similar behavior. The Volvo workshop thinks I should first watch it when it gets worse, then replace the clutch. No guarantee anymore… Greetings Michael
