Moin love Volvo friends, so I have to say I really like my S60 from 2005. He has only 142,000 km down and is all around in a good condition for a 16 year old car. Only one thing really goes on my cookie and clouds my joy at the car now: the seats crack! Above all the passenger seat, but since the latest also the driver seat a little. I have tried with the full leather sports seats already by now all possible seat settings. Whether at the top or at the bottom, at the front or at the back, they crack at load displacement. So speak in curves. It sounds like a metallic snap or a cracking stop. Sometimes several times per curve. It is also noticeable. I have the feeling it comes from the tracks. If necessary I can also try to record the whole thing by video. I have already completely removed the passenger seat and again installed it and paid attention to the fact that everything is properly tightened. Does not help. Does anyone know this problem and/or has ideas what could be done there? I would really be grateful for tips, since this condition has never been upgraded to me.
