Outdoor mirror vibrating

Something is wrong with the forum – gives timeout and creates only the subject… Hello, my V70 D5 has started vibrating since 03.03.03 and now I have a good 23000 km on it. What annoyed me all the time is the right mirror which starts to vibrate from 160 km/h or on bumpy roads accordingly earlier. at the last inspection I had it done – at least I thought. Unfortunately it was worse afterwards than before. On my call to the workshop the master told me that the mirror is movable in a bracket that was manufactured with too great tolerance. Volvo gave the instruction to all vehicles this problem occurs and the customers should complain about a foam rubber under the mirror to solve the problem. No nice way to solve a problem. Volvo is it simply too expensive to replace all the mirror engines (must be such a unit) and then cause them to be such a mess! What have you done for experience in this regard and gave it any help with you? Was the unit already completely changed – if you need to answer that?
